Species

Nearly 100.

Tabebuia is a neotropical genus of about 100 species in the tribe Tecomeae of the family Bignoniaceae. The species range from northern Mexico and the Antilles south to northern Argentina and central Venezuela, including the Caribbean islands of Hispaniola (Dominican Republic and Haiti) and Cuba. Well-known common names include Ipê, Poui, trumpet trees and pau d'arco.

They are large shrubs and trees growing to 5 to 50 m (16 to 160 ft.) tall depending on the species; many species are dry-season deciduous but some are evergreen. The leaves are opposite pairs, complex or palmately compound with 3–7 leaflets.

Tabebuia is a notable flowering tree. The flowers are 3 to 11 cm (1 to 4 in.) wide and are produced in dense clusters. They present a cupular calyx campanulate to tubular, truncate, bilabiate or 5-lobed. Corolla colors vary between species ranging from white, light pink, yellow, lavender, magenta, or red. The outside texture of the flower tube is either glabrous or pubescentThe fruit is a dehiscent pod, 10 to 50 cm (4 to 20 in.) long, containing numerous—in some species winged—seeds. These pods often remain on the tree through dry season until the beginning of the rainy.

Species in this genus are important as timber trees. The wood is used for furniture, decking, and other outdoor uses. It is increasingly popular as a decking material due to its insect resistance and durability. By 2007, FSC-certified ipê wood had become readily available on the market, although certificates are occasionally forged.

Tabebuia is widely used as ornamental tree in the tropics in landscaping gardens, public squares, and boulevards due to its impressive and colorful flowering. Many flowers appear on still leafless stems at the end of the dry season, making the floral display more conspicuous. They are useful as honey plants for bees, and are popular with certain hummingbirds. Naturalist Madhaviah Krishnan on the other hand once famously took offense at ipé grown in India, where it is not native.

Lapacho teaThe bark of several species has medical properties. The bark is dried, shredded, and then boiled making a bitter or sour-tasting brownish-colored tea. Tea from the inner bark of Pink Ipê (T. impetiginosa) is known as Lapacho or Taheebo. Its main active principles are lapachol, quercetin, and other flavonoids. It is also available in pill form. The herbal remedy is typically used during flu and cold season and for easing smoker's cough. It apparently works as expectorant, by promoting the lungs to cough up and free deeply embedded mucus and contaminants. However, lapachol is rather toxic and therefore a more topical use e.g. as antibiotic or pesticide may be advisable. Other species with significant folk medical use are T. alba and Yellow Lapacho (T. serratifolia)

Tabebuia heteropoda, T. incana, and other species are occasionally used as an additive to the entheogenic drink Ayahuasca.

Mycosphaerella tabebuiae, a plant pathogenic sac fungus, was first discovered on an ipê tree.

A sua conservação vem sendo estudada em termos de determinação da condição ideal de armazenamento, e tem demonstrado a importância de se conhecer o comportamento da espécie quando armazenada com diferentes teores de umidade inicial, e a umidade de equilíbrio crítica para a espécie (KANO; MÁRQUEZ & KAGEYAMA, 1978). As levíssimas sementes aladas da espécie não necessitam de quebra de dormência. Podem apenas ser expostas ao sol por cerca de 6 horas e semeadas diretamente nos saquinhos. A germinação ocorre após 30 dias e de 80%. As sementes são ortodoxas e há aproximadamente 72 000 sementes em cada quilo.

O desenvolvimento da planta é rápido.

Como outros ipês, a madeira é usada em tacos, assoalhos, e em dormentes e postes. Presta-se também para peças torneadas e instrumento musicais.

Tabebuia alba (Ipê-Amarelo)

Texto, em português, produzido pela Acadêmica Giovana Beatriz Theodoro Marto

Supervisão e orientação do Prof. Luiz Ernesto George Barrichelo e do Eng. Paulo Henrique Müller

Atualizado em 10/07/2006

O ipê amarelo é a árvore brasileira mais conhecida, a mais cultivada e, sem dúvida nenhuma, a mais bela. É na verdade um complexo de nove ou dez espécies com características mais ou menos semelhantes, com flores brancas, amarelas ou roxas. Não há região do país onde não exista pelo menos uma espécie dele, porém a existência do ipê em habitat natural nos dias atuais é rara entre a maioria das espécies (LORENZI,2000).

A espécie Tabebuia alba, nativa do Brasil, é uma das espécies do gênero Tabebuia que possui “Ipê Amarelo” como nome popular. O nome alba provém de albus (branco em latim) e é devido ao tomento branco dos ramos e folhas novas.

As árvores desta espécie proporcionam um belo espetáculo com sua bela floração na arborização de ruas em algumas cidades brasileiras. São lindas árvores que embelezam e promovem um colorido no final do inverno. Existe uma crença popular de que quando o ipê-amarelo floresce não vão ocorrer mais geadas. Infelizmente, a espécie é considerada vulnerável quanto à ameaça de extinção.

A Tabebuia alba, natural do semi-árido alagoano está adaptada a todas as regiões fisiográficas, levando o governo, por meio do Decreto nº 6239, a transformar a espécie como a árvore símbolo do estado, estando, pois sob a sua tutela, não mais podendo ser suprimida de seus habitats naturais.

Taxonomia

Família: Bignoniaceae

Espécie: Tabebuia Alba (Chamiso) Sandwith

Sinonímia botânica: Handroanthus albus (Chamiso) Mattos; Tecoma alba Chamisso

Outros nomes vulgares: ipê-amarelo, ipê, aipê, ipê-branco, ipê-mamono, ipê-mandioca, ipê-ouro, ipê-pardo, ipê-vacariano, ipê-tabaco, ipê-do-cerrado, ipê-dourado, ipê-da-serra, ipezeiro, pau-d’arco-amarelo, taipoca.

Aspectos Ecológicos

O ipê-amarelo é uma espécie heliófita (Planta adaptada ao crescimento em ambiente aberto ou exposto à luz direta) e decídua (que perde as folhas em determinada época do ano). Pertence ao grupo das espécies secundárias iniciais (DURIGAN & NOGUEIRA, 1990).

Abrange a Floresta Pluvial da Mata Atlântica e da Floresta Latifoliada Semidecídua, ocorrendo principalmente no interior da Floresta Primária Densa. É característica de sub-bosques dos pinhais, onde há regeneração regular.

Informações Botânicas

Morfologia

As árvores de Tabebuia alba possuem cerca de 30 metros de altura. O tronco é reto ou levemente tortuoso, com fuste de 5 a 8 m de altura. A casca externa é grisáceo-grossa, possuindo fissuras longitudinais esparas e profundas. A coloração desta é cinza-rosa intenso, com camadas fibrosas, muito resistentes e finas, porém bem distintas.

Com ramos grossos, tortuosos e compridos, o ipê-amarelo possui copa alongada e alargada na base. As raízes de sustentação e absorção são vigorosas e profundas.

As folhas, deciduais, são opostas, digitadas e compostas. A face superior destas folhas é verde-escura, e, a face inferior, acinzentada, sendo ambas as faces tomentosas. Os pecíolos das folhas medem de 2,5 a 10 cm de comprimento. Os folíolos, geralmente, apresentam-se em número de 5 a 7, possuindo de 7 a 18 cm de comprimento por 2 a 6 cm de largura. Quando jovem estes folíolos são densamente pilosos em ambas as faces. O ápice destes é pontiagudo, com base arredondada e margem serreada.

As flores, grandes e lanceoladas, são de coloração amarelo-ouro. Possuem em média 8X15 cm.

Quanto aos frutos, estes possuem forma de cápsula bivalvar e são secos e deiscentes. Do tipo síliqua, lembram uma vagem. Medem de 15 a 30 cm de comprimento por 1,5 a 2,5 cm de largura. As valvas são finamente tomentosas com pêlos ramificados. Possuem grande quantidade de sementes.

As sementes são membranáceas brilhantes e esbranquiçadas, de coloração marrom. Possuem de 2 a 3 cm de comprimento por 7 a 9 mm de largura e são aladas.

Reprodução

A espécie é caducifólia e a queda das folhas coincide com o período de floração. A floração inicia-se no final de agosto, podendo ocorrer alguma variação devido a fenômenos climáticos. Como a espécie floresce no final do inverno é influenciada pela intensidade do mesmo. Quanto mais frio e seco for o inverno, maior será a intensidade da florada do ipê amarelo.

As flores por sua exuberância, atraem abelhas e pássaros, principalmente beija-flores que são importantes agentes polinizadores. Segundo CARVALHO (2003), a espécie possui como vetor de polinização a abelha mamangava (Bombus morio).

As sementes são dispersas pelo vento.

A planta é hermafrodita, e frutifica nos meses de setembro, outubro, novembro, dezembro, janeiro e fevereiro, dependendo da sua localização. Em cultivo, a espécie inicia o processo reprodutivo após o terceiro ano.

Ocorrência Natural

Ocorre naturalmente na Floresta Estaciobal Semidecicual, Floresta de Araucária e no Cerrado.

Segundo o IBGE, a Tabebuia alba (Cham.) Sandw. é uma árvore do Cerrado, Cerradão e Mata Seca. Apresentando-se nos campos secos (savana gramíneo-lenhosa), próximo às escarpas.

Clima

Segundo a classificação de Köppen, o ipê-amarelo abrange locais de clima tropical (Aw), subtropical úmido (Cfa), sutropical de altitude (Cwa e Cwb) e temperado.

A T.alba pode tolerar até 81 geadas em um ano. Ocorre em locais onde a temperatura média anual varia de 14,4ºC como mínimo e 22,4ºC como máximo.

Solo

A espécie prefere solos úmidos, com drenagem lenta e geralmente não muito ondulados (LONGHI, 1995).

Aparece em terras de boa à média fertilidade, em solos profundos ou rasos, nas matas e raramente cerradões (NOGUEIRA, 1977).

Pragas e Doenças

De acordo com CARVALHO (2003), possui como praga a espécie de coleópteros Cydianerus bohemani da família Curculionoideae e um outro coleóptero da família Chrysomellidae. Apesar da constatação de elevados índices populacionais do primeiro, os danos ocasionados até o momento são leves. Nas praças e ruas de Curitiba - PR, 31% das árvores foram atacadas pela Cochonilha Ceroplastes grandis.

ZIDKO (2002), ao estudar no município de Piracicaba a associação de coleópteros em espécies arbóreas, verificou a presença de insetos adultos da espécie Sitophilus linearis da família de coleópteros, Curculionidae, em estruturas reprodutivas. Os insetos adultos da espécie emergiram das vagens do ipê, danificando as sementes desta espécie nativa.

ANDRADE (1928) assinalou diversas espécies de Cerambycidae atacando essências florestais vivas, como ingazeiro, cinamomo, cangerana, cedro, caixeta, jacarandá, araribá, jatobá, entre outras como o ipê amarelo.

A Madeira

A Tabebuia alba produz madeira de grande durabilidade e resistência ao apodrecimento (LONGHI,1995).

MANIERI (1970) caracteriza o cerne desta espécie como de cor pardo-havana-claro, pardo-havan-escuro, ou pardo-acastanhado, com reflexos esverdeados. A superfície da madeira é irregularmente lustrosa, lisa ao tato, possuindo textura media e grã-direita.

Com densidade entre 0,90 e 1,15 grama por centímetro cúbico, a madeira é muito dura (LORENZI, 1992), apresentando grande dificuldade ao serrar.

A madeira possui cheiro e gosto distintos. Segundo LORENZI (1992), o cheiro característico é devido à presença da substância lapachol, ou ipeína.

Usos da Madeira

Sendo pesada, com cerne escuro, adquire grande valor comercial na marcenaria e carpintaria. Também é utilizada para fabricação de dormentes, moirões, pontes, postes, eixos de roda, varais de carroça, moendas de cana, etc.

Produtos Não-Madeireiros

A entrecasca do ipê-amarelo possui propriedades terapêuticas como adstringente, usada no tratamento de garganta e estomatites. É também usada como diurético.

O ipê-amarelo possui flores melíferas e que maduras podem ser utilizadas na alimentação humana.

Outros Usos

É comumente utilizada em paisagismo de parques e jardins pela beleza e porte. Além disso, é muito utilizada na arborização urbana.

Segundo MOREIRA & SOUZA (1987), o ipê-amarelo costuma povoar as beiras dos rios sendo, portanto, indicado para recomposição de matas ciliares. MARTINS (1986), também cita a espécie para recomposição de matas ciliares da Floresta Estacional Semidecidual, abrangendo alguns municípios das regiões Norte, Noroeste e parte do Oeste do Estado do Paraná.

Aspectos Silviculturais

Possui a tendência a crescer reto e sem bifurcações quando plantado em reflorestamento misto, pois é espécie monopodial. A desrrama se faz muito bem e a cicatrização é boa. Sendo assim, dificilmente encopa quando nova, a não ser que seja plantado em parques e jardins.

Ao ser utilizada em arborização urbana, o ipê amarelo requer podas de condução com freqüência mediana.

Espécie heliófila apresenta a pleno sol ramificação cimosa, registrando-se assim dicotomia para gema apical. Deve ser preconizada, para seu melhor aproveitamento madeireiro, podas de formação usuais (INQUE et al., 1983).

Produção de Mudas

A propagação deve realizada através de enxertia.

Os frutos devem ser coletados antes da dispersão, para evitar a perda de sementes. Após a coleta as sementes são postas em ambiente ventilado e a extração é feita manualmente. As sementes do ipê amarelo são ortodoxas, mantendo a viabilidade natural por até 3 meses em sala e por até 9 meses em vidro fechado, em câmara fria.

A condução das mudas deve ser feita a pleno sol. A muda atinge cerca de 30 cm em 9 meses, apresentando tolerância ao sol 3 semanas após a germinação.

Sementes

Os ipês, espécies do gênero Tabebuia, produzem uma grande quantidade de sementes leves, aladas com pequenas reservas, e que perdem a viabilidade em poucos dias após a sua coleta. A sua conservação vem sendo estudada em termos de determinação da condição ideal de armazenamento, e tem demonstrado a importância de se conhecer o comportamento da espécie quando armazenada com diferentes teores de umidade inicial, e a umidade de equilíbrio crítica para a espécie (KANO; MÁRQUEZ & KAGEYAMA, 1978).

As levíssimas sementes aladas da espécie não necessitam de quebra de dormência. Podem apenas ser expostas ao sol por cerca de 6 horas e semeadas diretamente nos saquinhos. A quebra natural leva cerca de 3 meses e a quebra na câmara leva 9 meses. A germinação ocorre após 30 dias e de 80%.

As sementes são ortodoxas e há aproximadamente 87000 sementes em cada quilo.

Preço da Madeira no Mercado

O preço médio do metro cúbico de pranchas de ipê no Estado do Pará cotado em Julho e Agosto de 2005 foi de R$1.200,00 o preço mínimo, R$ 1509,35 o médio e R$ 2.000,00 o preço máximo (CEPEA,2005).

"This is a cosmopolitan genus, occurring in alpine habitats of temperate regions of Asia, Europe and the Americas. Some species also occur in northwest Africa, eastern Australia and New Zealand. They consist of annual, biennial and perennial plants. Some are evergreen, others are not.

"The name is a tribute to Gentius, an Illyrian king who was thought to have found out that the herbs had tonic properties." (Wikipedia)

"Gentians have opposite leaves that are sometimes arranged in a basal rosette, and trumpet-shaped flowers that are usually deep blue or azure, but may vary from white, creamy and yellow to red. Many species also show considerable polymorphism with respect to flower color. Typically, blue-flowered species predominate in the Northern Hemisphere, with red-flowered species dominant in the Andes (where bird pollination is probably more heavily favored by natural selection). White-flowered species are scattered throughout the range of the genus but dominate in New Zealand. All gentian species have terminal tubular flowers and most are pentamerous, i.e. with 5 corolla lobes (petals), and 5 sepals, but 4-7 in some species. The style is rather short or absent. The corolla shows folds (= plicae) between the lobes. The ovary is mostly sessile and has nectary glands." (Wikipedia)

In traditional Chinese medicine, G. tibetica is used to treat rheumatoid arthritis and to calm nervousness.

Little Blue Eyes 21/365 by Autumn S

Eye color is a polygenic trait and is determined by the amount and type of pigments in the eye's iris. Humans and animals have many phenotypic variations in eye color. In human eyes, these variations in color are attributed to varying ratios of eumelanin produced by melanocytes in the iris.The brightly colored eyes of many bird species are largely determined by other pigments, such as pteridines, purines, and carotenoids.

Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma. In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin. Color variations among different irises are typically attributed to the melanin content within the iris stroma.The density of cells within the stroma affects how much light is absorbed by the underlying pigment epithelium. OCA2 gene polymorphism, close to proximal 5′ regulatory region, explains most human eye-color variation.

Polycaprolactone beads by Nicholas Stevens

1

A wonderful material! See en.wikipedia.org/wiki/Polycaprolactone for more details. This softens at 62 degrees C, and so you can just drop the beads into hot water and when they go clear, then just take them out, squeeze out the water and shape by hand. They don't burn, but get a grown up to help if you have very thin skin. This stuff is sold as 'Polymorph' and Maplins will charge you £18 for 500g, or online you can pay just over half that. These are lit from below by a strong flash. The initial reason is that the background was full of people bending over and talking to children, children, and various forms of chaos, so I though, why not make it all turn black? Once I tried it however, I liked the look, and went off to find more things to photgraph this way.

Conception, scénographie, chorégraphie et interprétation Pierre Rigal

Créée au Gate Theatre de Londres en 2008, cette performance chorégraphique - jouée plus de 200 fois dans le monde - inspirée par des textes de Edgar Keret, met en scène un inquiétant dandy, mannequin polymorphe mu par l’enchaînement standardisé de ses propres automatismes, mais aussi par les rouages de son étroit espace vital. Absurde, drôle et angoissant, Pierre Rigal met sous presse la menaçante banalité de l’homme contemporain.

Coleopteroid rhyparochromid bug. by Tony

2 9

I thought this rhyparachromid bug was a black beetle when I first saw it climbing this concrete wall. It was pure shiny black and wings were of coleopteroid form. That is the wings met down the middle without overlapping. The corium (thickened portion) being enlarged with the membranous ends reduced to small flaps (barely visible - see note on pic). Thus also exsposing some of the rear abdominal segments.

Apparantly coleoptery occurs numerously across Lygaeoidea in Australia but noticeably so in rhyparachromids. Slater (1975) observed a greater occurance of this form in these bugs found in exposed hot xeric habitat and thus suggests it is an insulation adaptation.

Leafcutting Ant CDODDS_J1X5037 by Christopher Dodds

1

Leaf-cutter ants have powerful jaws which vibrate a thousand times a second to slice off pieces of leaf. Size for size, their bodies are amazingly powerful, able to carry pieces of leaf that weigh at least 20 times their own body weight - that's the same as a human carrying a one ton load. Like bees, their colonies contain different sorts of workers. Soldier leaf-cutters have huge jaws, strong enough to cut through leather and gardener leaf-cutters work beneath ground and process the pieces of the leaf that the harvesters bring back. The nest also contains a queen and she lays all the eggs needed to keep the colony supplied with new workers. Leaf-cutting ants cannot eat leaves. Instead, they carry the cut pieces back to the nest and use it as compost to cultivate the fungus. The fungus cannot survive outside the nest or reproduce without the ants help. Amazingly, if the ants collect plant material that is toxic to the fungus, the fungus seems to release a chemical signal which stops the ants collecting that particularly plant material. There can be three to eight million ants in a single colony, which can measure 15 m across and 5 m deep. The ants forage for leaves some distance from their nest. They find their way home by producing and laying down pheromone (scent) trails as they move away from the nest. These pheromones are so powerful that each ant produces only one billionth of a gram. One gram of this pheromone would easily be enough to make an ant trail all around the world. Leaf-cutting ants harvest more greenery in South American forests than any other animal. In fact, within the rain forest, leaf-cutter ants consume almost 20% of the annual vegetation growth! In its lifetime, a colony of these ants may move over 20 tons of soil.

Teapotty on display in a cabinet at the V&A by Rain Rabbit

Teapotty! is an interactive electronic teapot I've constructed for the Chi-TEK tech tea party event at the V&A in Sept 11. Before and after the tea party, it will sit quietly on display in a cabinet for 3 months. www.mztek.org/programs/chi-tek/

Teapotty! is a teapot sitting on a servo which takes readings from a magnetometer which is influenced by neodymium magnets in a cup. The magnetometer takes the reading from the north position, plays a bit of something similar to the Tetley Tea tune and then moves to a new position - where the teacup moves to. BlinkM RGB LEDs indicate the new position of the teapot by changing colour based on the teapot's new position from 0-180 degrees. I made some polymorph diffuser covers for them & also added heart confetti to emphasise the feeling of heartwarming happiness a cup of tea can bring :-)

Muonionalusta

The Muonionalusta is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE. The first fragment of the Muonionalusta was found in 1906 near the village of Kitkiöjärvi. Around forty pieces are known today, some being quite large. Other fragments have been found in a 25-by-15-kilometre (15.5 mi × 9.3 mi) area in the Pajala district of Norrbotten County, approximately 140 kilometres (87 mi) north of the Arctic Circle. The meteorite was first described in 1910 by Professor A. G. Högbom, who named it "Muonionalusta", after a nearby place on the Muonio River. It was studied in 1948 by Professor Nils Göran David Malmqvist. The Muonionalusta, probably the oldest known meteorite (4.5653 billion years), marks the first occurrence of stishovite in an iron meteorite.

Description

Studies have shown it to be the oldest discovered meteorite impacting the Earth during the Quaternary Period, about one million years ago. It is quite clearly part of the iron core or mantle of a planetoid, which shattered into many pieces upon its fall on our planet. Since landing on Earth the meteorite has experienced four ice ages. It was unearthed from a glacial moraine in the northern tundra. It has a strongly weathered surface covered with cemented faceted pebbles.

Composition

ew analysis of this strongly shock-metamorphosed iron meteorite has shown a content of 8.4% nickel and trace amounts of rare elements—0.33 ppm gallium, 0.133 ppm germanium and 1.6 ppm iridium. It also contains the minerals chromite, daubréelite, schreibersite, akaganéite and inclusions of troilite. For the first time, analysis has proved the presence of a form of quartz altered by extremely high pressure—stishovite, probably a pseudomorphosis after tridymite. From the article "First discovery of stishovite in an iron meteorite": Stishovite, a high pressure polymorph of SiO2, is an exceptionally rare mineral...and has only been found in association with a few meteorite impact structures.... Clearly, the meteoritic stishovite cannot have formed by isostatic pressure prevailing in the core of the parent asteroid.... One can safely assume then that stishovite formation (in the Muonionalusta meteorite) is connected with an impact event. The glass component might have formed directly as a shock melt....

A 2010 study reported the lead isotope dating in the Muonionalusta meteorite and concluded the stishovite was from an impact event hundreds of millions of years ago: "The presence of stishovite signifies that this meteorite was heavily shocked, possibly during the 0.4 Ga [billion years] old breakup event indicated by cosmic ray exposure...."

Jaborosa integrifolia (Argentinian shrub) by Luigi Strano

3 22

Jaborosa integrifolia exhibits stigma-height polymorphism. There are individuals with flowers where anthers and stigma are at the same height but the rule is variable herkogamy, the most common type (75%) being that with an exerted stigma. Self- and cross-tubes did not differ in their capability to reach the ovary.There is not autogamy but mostly self-incompatibility. Fruits from controlled cross-pollination showed the highest seed set and seed viability. The nectar sugar is characterized by a similar amount of glucose and fructose, and by the absence of sucrose. Although nectar secretion was continuous throughout the life of the flower, most nectar was secreted during the first 24 h after flower opening.

La Jaborosa integrifolia è una pianta rizomatosa di origine argentina.Cresce eretta e sviluppa un corto fusto che porta una piccola chioma, in genere tondeggiante. Jaborosa integrifolia è un arbusto sempreverde

Partially devitrified rhyolitic obsidian with lithophysae (Roaring Mountain Member, Plateau Rhyolite, Upper Pleistocene, ~59 ka; Obsidian Cliff, Yellowstone, Wyoming, USA) 2 by James St. John

Obsidian in the Pleistocene of Wyoming, USA.

Obsidian is a glassy-textured, extrusive igneous rock. Glassy-textured rocks have no crystals at all. They form by very rapid cooling of lava or by cooling of high-viscosity lava. Most obsidians form by the latter. Obsidian can be felsic, intermediate, mafic, or alkaline in chemistry. Most are felsic to intermediate.

A famous locality in North America is Obsidian Cliff at Yellowstone, Wyoming. It is a Pleistocene-aged lava flow with the chemistry of rhyolite (= a light-colored, felsic, aphanitic, extrusive igneous rock). The cliff itself shows columnar jointing. The rocks principally range from aphyric rhyolitic obsidian to partially devitrified rhyolitic obsidian. Lithophysae are sometimes present. Extremely small, microscopic crystals are present - they can be seen in thin sections. Some samples are reported to have small olivine phenocrysts. Small clusters of crystals, composed of plagioclase feldspar, pyroxene, and olivine, are sometimes present.

Many of the whitish-colored spots and bands running through most Obsidian Cliff rock samples are areas of devitrification. Glass is unstable on geologic times scales and it slowly crystallizes. The light-colored spots and bands are now non-glassy. Spotted, partially devitrified obsidian is known by the rockhound term "snowflake obsidian" (see: www.flickr.com/photos/jsjgeology/16561606417). The spots are composed of silica (SiO2), but are not quartz. Rather, they are composed of a polymorph of quartz - cristobalite.

The subrounded cavities are lithophysae - they formed before the rock completely solidified. The original lava flow had some subspherical structures known as spherulites, composed of glassy to cryptocrystalline material (many felsic extrusive igneous rocks have these). Expanding gases in the spherulites destroyed this material, resulting in partially empty spaces.
