What is shale rock
Oil shale is a dirty and expensive source of unconventional oil. Oil shale is a mixture of sand, silt, salt, and an insoluble organic substance called kerogen. Rock-like at room temperature, oil shale produces vapors and gases when heated, which in turn are condensed and turned into oil. Oil shale shouldn't be confused with "shale oil," also ...Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al 2 Si 2 O 5 ( OH) 4) and tiny fragments ( silt -sized particles) of other minerals, especially quartz and calcite. [1]Shale is a sedimentary rock that contains layers of clay sediment. This rock is generally found in the bottom of lagoons, lakes, oceans, and swamps...

Shale is a lithified mud — a sedimentary rock composed mostly of clay- and silt-sized grains. There are several ways to define shale. Some definitions are rather narrow. Glossary of Geology published by the American Geological Institute defines shale as a laminated, indurated rock with >67% clay-sized minerals 1. This definition clearly ...Shale is a fine-grained sedimentary rock that forms when silt and clay-size mineral particles are compacted, and it is easily broken into thin, parallel layers. Black shale contains organic material that can generate oil and natural gas, which is trapped within the rock's pores.

It is famous for a extensive form of makes use of such as roofing, floors, and flagging due to its sturdiness and appealing look. Colour: Variable colour – black, blue, green, red, brown and buff.Oil Shale Classification. Classification are generally classified by their mineral content and depositional history. Depositional history of a sedimentary rocks is type of enbironment in which rock developed.The depositional history of an oil shale includes the organisms and sediments that were deposited, as well as how those deposits interacted with pressure and heat.Oct 9, 2019 · Shale can be fairly hard if it has a silica cement, making it closer to chert. Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate.
