What rock is shale.
Shale is a clay-rich sedimentary rock found all over the world. If shale gets wet, it usually smells like mud or wet dirt. However, the rock known as oil shale has a smell like diesel oil or tar. That oily smell is from a petroleum-like substance known as kerogen. Kerogen is not yet oil.

Oil shale is a term referring to any sedimentary rock that contains materials such as paraffin hydrocarbons.Physical properties. Dolomite crystals are colourless, white, buff-coloured, pinkish, or bluish. Granular dolomite in rocks tends to be light to dark gray, tan, or white. Dolomite crystals range from transparent to translucent, but dolomite grains in rocks are typically translucent or nearly opaque. The lustre ranges from subvitreous to dull.
Lutgens and Tarbuck provide a useful table of some of the varieties of metamorphic rock. ... Shale, granitic and volcanic rocks, Coarse-grained, non-micaceous.
Location. Floor 1. There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.Shale is a fine-grained sedimentary rock that is formed when silt and clay are compressed. It is composed of many thin layers, and it readily splits into thin pieces where these layers meet—making it a relatively brittle stone. [2] Shale is composed of small grains and various minerals along with organic particles.Shale is a soft, brittle, fine-grained, and easily eroded sedimentary rock formed from mineral-rich silt, or mud, that was deposited in an aquatic environment, buried by other sediment, and compacted and cemented into hard rock. When exposed at the surface by erosion, shale weathers into thin layers called plates.The lowest layer is Organ Rock Shale, the middle is de Chelly Sandstone, and the top layer is the Moenkopi Formation, capped by Shinarump Conglomerate. West and East Mitten Buttes are two distinctive geological features found within the Monument Valley Navajo Tribal Park in northeast Navajo County, Arizona.
Fracking (also known as hydraulic fracturing, fracing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a …
