Oil shale is the rock from which shale oil is extracted. Shale oil is similar to petroleum, and can be refined into many different substances, including diesel fuel, gasoline, and liquid petroleum gas ( LPG ). 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.Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. There are two types of sedimentary rocks: Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,

Red beds. Red beds of the Permo-Triassic Spearfish formation surround Devils Tower National Monument. Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain ...Shale. Shale is a sedimentary rock composed of very fine clay particles. Clay forms from the decomposition of the mineral feldspar. Other minerals present in shale are quartz, mica, pyrite, and organic matter.

Shale. Our final clastic rock type is the most common type of all five: shale rocks. These rocks are the thinnest type and are identified as sedimentary rocks that have been laminated and composed of fine-grained materials. Like many of the other types, quartz is a common element in shale rocks.The best known and most commonly seen metamorphic rocks are those produced by Barrovian (also called regional) metamorphism. Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, and then through phyllite, schist, and gneiss. It can be hard to imagine at first that all these very ...
