Rocks are what the crust of the earth is made of. They are the mountains and the bottom of the ocean. They are everywhere on earth, but often buried under soil. Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral.Oil shale is just one unconventional oil source that's being researched.

Shale is a fine-grained sedimentary rock composed primarily of clay minerals and other clay-sized particles of minerals like quartz and calcite. It is laminated and fissile, easily breaking along bedding planes. Shale forms from the deposition and compaction of clay-sized minerals in a low-energy environment. Composed of shales, sandstones, and conglomerates. Torrey sand and Delmar sand [members] mapped undivided, and Rose Canon shale [members] separately mapped on geologic map of La Jolla quad, San Diego Co, CA. Thickness of Delmar is about 200 feet; thickness of Torrey approximately 25 to 200 feet and Rose Canon about 300 feet.Most of the production increases since 2005 are the result of horizontal drilling and hydraulic fracturing techniques, notably in shale, sandstone, carbonate, and other tight geologic formations. Natural gas is produced from onshore and offshore natural gas and oil wells and from coalbeds. In 2022, U.S. dry natural gas production was about 10.8 ... Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz.
The only difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. Both are made of ancient mud. From the point of view of understanding the ancient conditions of sediment deposition, it is more useful to subdivide mud rocks into siltstone and ...This formation consists of sandstone and shale composed of quartz, hematite, and clay. The symmetrical ripples on the surface, dinosaur footprints, suggest that the area was a beach near water. The top of the Dakota formation ...Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1] [2] The term mudstone is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. [3]…

During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids.
