Location
Ganh Da Dia is a small area of interlocking basalt columns sitting at the coast of Tuy An District, Phu Yen Province, Vietnam, which is about 600 km from Ho Chi Minh City. The special rock formation comprises of round and pentagon dishes, stacking on top one another hence its name "Ganh Da Dia" means dish rock promotory in vietnamese. According to scientists, this extrusive volcanic rock was a result of an ancient volcanic eruption, caused by the fast cooling of lava at the surface of the sea. There is another site like this in Ireland and that is the Giant's Causeway.
Time
I arrived before sunrise at 4:00 am when it was still dark. There was a rain on the night before and I was worry that the sun might not come out due to lots of clouds in the sky. However, it finally started to glow and the sunrise was nothing short of a fantastic light show.
Techniques
2-stop hard step grad ND filter for darkening the brighter sky and bringing it into balance with the darker foreground rock.
Circular polarizer filter for increasing the overall color saturation and controlling the reflection on the wet rock.
Hyperfocal distance focusing at 1.6m for fullframe 16mm at f/5.6

Rock No. 15555 (left) was collected by Apollo 15 in 1971 about 450 miles north of the lunar equator in an area called the Hadley-Apennine Mountains--a mountain range higher than the Himalayas. It is a basalt from this area and is a medium-coarse grand igneous rock formed by the cooling of molten lava.
Rock No. 15498 (right) was also collected also collected by Apollo 15 in the Dune Crater of the same mountain range. It is a breccia, which forced when meteorites hit the surface about 4 billion year ago. The high pressures and temperatures that resulted from the meteorite impacts literally remelted, crushed and mixed the layers of the original lunar crust and welded the existing rocks and soils together to create breccia.
Space Center Houston’s Lunar Samples Vault in the Starship Gallery is the largest public display of moon rocks in the world. A certified clean room with the same equipment used in the Lunar Sample Laboratory Facility, actual moon rocks are kept in a pure nitrogen environment for preservation.
Space Center Houston is the official visitor center of NASA Johnson Space Center and a Smithsonian Affiliate Museum owned and operated by the nonprofit Manned Spaceflight Education Foundation. The center opened in 1992 and hosts more than 1 million visitors annually in its 250,000-square-foot educational complex with over 400 space artifacts, permanent and traveling exhibits, attractions, live shows and theaters dedicated to preserving the history of America's human spaceflight program.
The Lyndon B. Johnson Space Center (JSC) is the National Aeronautics and Space Administration's Manned Spacecraft Center, where human spaceflight training, research, and flight control are conducted. Construction of the center, designed by Charles Luckman, began in 1962 and the 1,620-acre facility officially opened for business in September 1963. The center is home to NASA's astronaut corps, and is responsible for training astronauts from both the U.S. and its international partners. It has become popularly known for its flight control function, identified as "Mission Control" during the Gemini, Apollo, Skylab, Apollo–Soyuz, and Space Shuttle program flights. It is also the site of the former Lunar Receiving Laboratory, where the first astronauts returning from the Moon were quarantined, and where the majority of lunar samples are stored.

Results in rock that is harder and more brittle than the surrounding basalt. This in turn may cause it to erode slower or faster than surrounding rock.

Cliff-side outcropping of pillow basalt (extrusive volcanic rock) along the west side of the port facilities at Port San Luis, north end of San Luis Obispo Bay, between San Luis Obispo and Pismo Beach (Central Coast), California. Pillow basalts form during underwater volcanic eruptions (see Kilauea, Hawaii). These rocks are deep-water Franciscan, probably Jurassic-Cretaceous in age. This was a completely unexpected find for me so I only had my Iphone and the sun was in a bad position for photographing this, but it was such a spectacular outcrop that I had to grab some photos to share.

Basalt, an extrusive igneous rock, often has gas bubbles trapped in it as the lava cooled and solidified. If the lava was in the process of flowing the gas bubbles can be stretched out as in this specimen. Many years after the solidification of the basalt, groundwater transported minerals to the open cavities and deposited the materials it carried in solution in them. In this case it was quartz. The streamlined shape of the quartz nodules in the basalt has given the amygdaloidal to the basalt. The term amygdaloidal is from the Latin word amygdala, meaning “almond.”

Twin explorers examine the Cardenas basalt exposure in Carbon Canyon, mile 65 in the Grand Canyon. The formation is named after a Spanish explorer who may have been the first European to see the canyon. There's a memorable scene in the IMAX film showing his surprise at his first look over the south rim. From 35mm slide, April 1987.
The Cardenas basalts underlie all the sedimentary layers in the Grand Canyon, meaning they are the oldest deposits above the bedrock. Yet radiometric dating tests showed a spread of ages, some of which resulted in "younger" ages (by millions of years) than some of the lavas on top of the Grand Canyon, which logically must have been the very youngest of all. The reputable lab doing the dating had not been told where the samples came from, so no dating bias entered into their analysis. This discrepancy points out serious doubts about the reliability of radiometric dating techniques in some situations.
These twin guys on the trip dressed like old west pioneers, but we found out they were in business together creating pipes for pipe organs.

I dared not go any further. There was a steep drop to the right and no hand rail past the entrance. The basalt was extremely slippery due to the rain. Some of it was painted with non-slip paint, but I didn't trust my balance.

Amygdaloidal basalt is a vesicular basalt that has had the original vesicles (gas bubbles in lava) subsequently filled with secondary minerals.
Stratigraphy: unrecorded (but possibly eroded from the Portage Lake Volcanic Series, Bergland Group, middle Keweenawan Supergroup, upper Mesoproterozoic, 1.093 to 1.097 Ga)
Locality: water-worn clast from an unrecorded site (but possibly from the shoreline of Lake Superior)

---------------------------------
Igneous rocks form by the cooling and crystallization of hot, molten rock (magma / lava). If this happens at or near the land surface, or on the seafloor, they are extrusive igneous rocks. If this happens deep underground, they are intrusive igneous rocks. Most igneous rocks have a crystalline texture, but some are clastic, vesicular, frothy, or glassy.
Basalt is a common extrusive igneous rock. Basalt is the dominant rock in Earth’s upper oceanic crust. Black lava rocks seen at famous volcanoes such as Mt. Kilauea in Hawaii and Mt. Etna in Sicily are composed of basalt. Basalt has a mafic chemistry. Mafic igneous rocks are generally dark-colored, have 45-52% silica (= SiO2 chemistry) (mafic has also been defined as 45 to 55% silica), are rich in iron (Fe), magnesium (Mg), and calcium (Ca), and are dominated by the minerals plagioclase feldspar, pyroxene, and sometimes olivine (this example has a greenish olivine component).
Basalts have an aphanitic texture (finely crystalline - all or almost all crystals are less than 1 millimeter in size each), but some are porphyritic or coarsely crystalline if the lava flow took time to cool and solidify (e.g., some Proterozoic basalt lavas in the Keweenaw Peninsula of Michigan's Upper Peninsula).
Vesicular basalts (e.g., the sample seen here) are essentially intermediate lithologies between basalts and scorias. Scorias are basaltic rocks with numerous small gas bubbles. Vesicular basalts are basaltic rocks having relatively few, relatively large gas bubbles. Vesicular basalt is more dense than scoria (some scorias will float on water; vesicular basalts won’t do that).

Ce nouveau tome des IGLS regroupe toutes les inscriptions grecques et latines du plateau du Lejā, vaste triangle basaltique au sud de Damas, que les Anciens nommaient le Trachôn, le « Rugueux », ce qui traduit bien son aspect sauvage et désolé. Ces inscriptions illustrent la vie dans l’Antiquité des villages de la région qui sont répartis à la fois sur le pourtour du plateau et sur le plateau lui-même, surtout dans la moitié sud, plus propice aux cultures. Les textes appartiennent à tous les genres habituels des inscriptions grecques, consécrations en l’honneur des dieux et déesses, dédicaces en l’honneur des empereurs et des agents impériaux de haut rang (gouverneurs notamment), commémorations de constructions publiques ou privées, épitaphes, bornes milliaires de la route romaine qui le traverse du nord au sud. Une partie de ces inscriptions avaient été publiées auparavant, trouvées par les voyageurs et savants qui ont parcouru la région depuis le début du XIXe siècle, mais une partie non négligeable sont des inédits, trouvés par les auteurs de ces volumes lors de leurs nombreuses visites sur le terrain.
This new volume of IGLS contains all the greek and latin inscriptions of the Leja, the large basaltic triangular plateau situated south of Damascus and which was called Trachôn, the « Rough », by ancient sources. This name gives a perfect image of this wilderness and desolated country. The inscriptions illustrate the life during the ancient greek and roman periods in the villages built around or on the plateau, specially in the south part, more cultivated. These texts are essentially religious consecrations, dedications for emperors or governors, commemorations of private or public buildings, epitaphs, milestones of the roman road crossing the plateau from north to south. Most of them have been published by travellers and scholars since the beginning of the XIXth century, but a big lot of them have been found by the authors of this book during their explorations of the country.
آني سارتر-فوريا وموريس سارتر
نقوش سورية اليونانية واللاتينية
هضبة التراخون
وأطرافها
يتضمن هذا الجزء من سلسلة “نقوش سورية اليونانية واللاتينية” كافة النقوش اليونانية والإغريقية في هضبة اللجاة، هذا المثلث البازلتي الذي يقع إلى الجنوب من دمشق والذي كان يطلق عليه قديماً اسم تراكونية أو “المنطقة الوعرة”، وهو اسم يصف جيدا الطبيعة القاسية والمقفرة لهذه الهضبة. تعطي هذه النقوش صورة كاملة عن الحياة القديمة في القرى الموجودة فوق الهضبة وفي محيطها خاصة في الجزء الجنوبي الأكثر خصوبة، وهي تنتمي إلى كافة الأنماط المعروفة من النقوش اليونانية، كتكريس الآلهة وإهداءات للأباطرة ولرجالات الإمبراطورية (وبالأخص حاكمي المقاطعات)، وكذلك الاحتفال ببناء الصروح العامة أو الخاصة والأضرحة والنصب العسكرية على الطريق الروماني الممتد من شمال الهضبة إلى جنوبها. قسم كبير من هذه النقوش التي تم نشرها سابقاً كان قد وجدها رحالة وباحثون جابوا هذه المنطقة في بدايات القرن التاسع عشر، لكن قسماً آخر لا يستهان به لم ينشر بعد، عثر عليه مؤلفو هذه الأجزاء اثناء زياراتهم المتكررة للموقع.
Basalt is extrusive volcanic rock, this pillow shape occurs when basalt erupts underwater.

I had visited Mount St. Helens a year after its 1980 eruption and brought home this pumice and basalt. They measure roughly 1-1/4 and 1-1/2 inches along their longest axes, respectively. Tonight's episode of the Weather Channel's Forecast Earth was dedicated to volcanoes, including the news that Mount St. Helens is forming another lava dome.
My visit -- including the sight of a fawn nibbling a spring-green shoot poking out of the ash -- had inspired this poem:
Sanctuary, Mount St. Helens
The softened grey plain under my feet
tames roaring magma. I sink gently,
in a free-fall
of weights made light
and unfamiliar,
buoyed in a slate tide,
poured in volcanic stasis.
The dull floor etches my footprints
in shattered glass, on a field
with no vanishing point --
and all around me
chipped, denuded peaks
change distance,
edge upon stark edge.
Today I must trust this mountain,
stepping carefully on muffled ground
cued to tremors, murmurs, the silence
of halted growth. A timid fern
curls around a dead, twisted birch woven
in a tangle of birches.
Wild greens lay their thin stalks
over macrames of charred wood
in gauzed lava, shaded
neither wholly black,
nor wholly white.
At any time, the earth might shake
and sway, sifting centuries of dust,
tripping young deer, swallowing pumice and wildflower,
and the air crackle with sirens
echoing like birds off the mountain face, or caught
in the hollowed bones of melting rock.
Below me are pulverized graves, layers
of life and death and
life again.
I hold my breath
to read quick
cryptic traces of seismic thoughts.
And if I stare outward long enough,
I can see new shoots from a simpler age
rise, reborn and ancient
out of motionless ash.
