Fluorite and calcite from Ohio, USA.
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are about 5400 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The halides are the "salt minerals", and have one or more of the following anions: Cl-, F-, I-, Br-.
Fluorite is a calcium fluoride mineral (CaF2). The most diagnostic physical property of fluorite is its hardness (H≡4). Fluorite typically forms cubic crystals and, when broken, displays four cleavage planes (also quite diagnostic). When broken under controlled conditions, the broken pieces of fluorite form double pyramids. Fluorite is a good example of a mineral that can be any color. Common fluorite colors include clear, purple, blue, green, yellow, orange, and brown. The stereotypical color for fluorite is purple. Purple is the color fluorite "should be". A mineral collector doesn't have fluorite unless it's a purple fluorite (!).
Fluorite occurs in association with some active volcanoes. HF emitted from volcanoes can react with Ca-bearing rocks to form fluorite crystals. Many hydrothermal veins contain fluorite. Much fluorite occurs in the vicinity of southern Illinois (Mississippi Valley-type deposits).

Phacops rana crassituberculata Stumm, 1953 - fossil trilobite from the Devonian of Ohio, USA. (Dave Mielke collection; temporary public display, Ohio Geological Survey, Columbus, Ohio, USA)
This fossil is also known as Eldredgeops rana crassituberculata.
Trilobites are extinct marine arthropods. They first appear in Lower Cambrian rocks and the entire group went extinct at the end of the Permian. Trilobites had a calcitic exoskeleton and nonmineralizing parts underneath (legs, gills, gut, etc.). The calcite skeleton is most commonly preserved in the fossil record, although soft-part preservation is known in some trilobites (Ex: Burgess Shale and Hunsruck Slate). Trilobites had a head (cephalon), a body of many segments (thorax), and a tail (pygidium). Molts and carcasses usually fell apart quickly - most trilobite fossils are isolated parts of the head (cranidium and free cheeks), individual thoracic segments, or isolated pygidia. The name "trilobite" was introduced in 1771 by Johann Ernst Immanuel Walch and refers to the tripartite division of the trilobite body - it has a central axial lobe that runs longitudinally from the head to the tail, plus two side lobes (pleural lobes).
Seen here is a famous trilobite whose remains are relatively common in the Middle Devonian-aged Silica Formation of northeastern Ohio. This is Phacops rana crassituberculata (also known as Eldredgeops, an unnecessary genus name based on taxonomic oversplitting). Phacops trilobite fossils occur with other typical Middle Paleozoic shallow marine invertebrates: brachiopods, bryozoans, crinoids, and corals.
Classification: Animalia, Arthropoda, Trilobita, Polymerida, Phacopidae

It was still quite cool and wet at this habitat at this time of year compared to Texas. Traces of snow could still be seen on the Kaibab Plateau.
This is by far one of the most interesting receptacles made and precedes the "T-Slot" Receptacle. This receptacle accepts parallel and tandem blade plugs. In the corner of the receptacle, the initials "J.I.P." are visible, denoting it's manufacturer: "John I. Paulding." Receptacles like this one are seen in catalogs dating as early as 1910. This particular receptacle was obtained from a Rowhouse in Reading, PA.
This is a small part of an Ohio wind farm we saw earlier this month. After visiting with my mother in Toledo, we drove through some of the places in NW Ohio whose names, at least, are familiar to me from my childhood, growing up near Lima. We went SW from Toledo through Defiance, Paulding, and Van Wert counties before heading to Lima for the night. Driving US 127 in Paulding and Van Wert counties, we came upon more of the huge, new windmills than I have seen in one place so far. This Paulding County shot shows just 11, but an April 2011 newspaper piece said two different ventures were erecting a total of 350 windmills in the two counties; it also stated that the towers in four sections, plus the blades (which are 311.7 feet above the ground) and that more than one tower per day can be put in place when weather is favorable. Best when viewed in the light box.
Ohio State Route 111 is a lovely rural byway that connects the Indiana-Ohio state line with the town of Defiance. It passes through portions of Paulding and Defiance counties.

During the Great Depression, family became even more important to everyone. Aside from religion, family was the only place people could turn to. People turned to their family for comfort. They were able to help each other because they knew what the others were going through. Like in this family portrait, families usually had a lot of people in them and they were very close. Because of the legal costs, couples delayed marriage and divorce rates also dropped dramatically. Also, for the first time in history, the birthrates dropped below the replacement level. However, in some cases, the families were not close and many times husbands walked out on their families. For the first time, men had to rely on their wives and their children to make ends meet. Many husbands could not handle the loss of power and walked out on their families. Although families went through hardships dealing with the Great Depression itself, they were not aware of the toll that it would take on their families. Despite all of these difficult things, family still remained a big part of most people’s lives.

Paulding is a village in and the county seat of Paulding County, Ohio, United States. It is located predominantly in Paulding Township. The population was 3,595 at the 2000 census. Paulding was a planned community, founded in 1848 at the center of the county, and named after the county by speculators who expected to profit by moving the county seat. In 1851, the county seat was moved from Charloe, which had been the county seat for a decade; prior to that, court was held at Rochester.
The town square is devoted to the courthouse, an orange brick structure surrounded by trees upon a spacious lawn. In the centennial year of 1876, the county commissioners determined to build a new courthouse, and visited many courthouses, finally deciding to erect a duplicate of the courthouse in Adrian, Michigan at a cost of $40,000. The courthouse was finished in 1886.
Paulding is largely a bedroom community.

Rock gypsum from the Devonian of Ohio, USA.
Sedimentary rocks form by the solidification of loose sediments. Loose sediments become hard rocks by the processes of deposition, burial, compaction, dewatering, and cementation.
There are three categories of sedimentary rocks:
1) Siliciclastic sedimentary rocks form by the solidification of sediments produced by weathering & erosion of any previously existing rocks.
2) Biogenic sedimentary rocks form by the solidification of sediments that were once-living organisms (plants, animals, micro-organisms).
3) Chemical sedimentary rocks form by the solidification of sediments formed by inorganic chemical reactions. Most sedimentary rocks have a clastic texture, but some are crystalline.
Rock gypsum (also known as gyprock) is a chemical sedimentary rock. It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO4·2H2O - hydrous calcium sulfate). Heating of gypsum or rock gypsum drives off the water, leaving only calcium sulfate behind (the mineral anhydrite). Adding water to anhydrite results in the formation of gypsum again.
Rock gypsum, unlike rock salt, does not have a salty taste, and is softer (H = 2) - it can be scratched with a fingernail. Rock gypsum’s color is often a mottled whitish-light grayish-light brownish. It is usually microcrystalline and powdery looking (it’s much finer-grained than typical rock salt deposits). Rock gypsum superficially resembles chalk. Chalk is calcitic, and so will bubble in acid - rock gypsum does not bubble in acid. Rock gypsum samples vary from extremely friable to moderately solid.

Hippocardia cunea (Conrad, 1840) - fossil rostroconch from the Devonian of Ohio, USA. (Dave Mielke collection; temporary public display, Ohio Geological Survey, Columbus, Ohio, USA)
This species is also known as Hoareicardia cunea.
Rostroconchs are an extinct class of molluscs. They are restricted to the Paleozoic - they first appear in Lower Cambrian rocks and go extinct in the Upper Permian. Rostroconchs somewhat resemble bivalves (= clams & relatives), but they are actually pseudobivalved. They have a continuous, univalved, calcareous shell roughly shaped like a taco. As the organism grows, it breaks the shell along a "hinge line" and recements the shell together. This can be seen as tiny breaks and cracks that have been resealed. True bivalves have two separate calcareous shells held together by organic material. Bivalves can readily open and shut their shells.
Rostroconchs had an inferred semi-infaunal lifestyle and, as a group, were likely deposit feeders or filter feeders or both. They had a permanent anterior gape (open space between the edges of the "two" shells and a posterior rostrum (= tubular extension of the shell). Some rostroconchs had a hood - an extension of shell material around the rostrum. The soft-part anatomy was probably clam-like. They had their greatest diversity during the Early Ordovician.
