Shale is a fine-grained, ... Most of the quartz is detrital (part of the original sediments that formed the shale) rather than authigenic (crystallized within the shale after deposition). ... In addition to this physical compaction, chemical compaction may take place via pressure solution. Zobacz więcej 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, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other … Zobacz więcej Shales are typically gray in color and are composed of clay minerals and quartz grains. The addition of variable amounts of minor constituents alters the color of the rock. Red, brown and green colors are indicative of ferric oxide (hematite – reds), iron hydroxide Zobacz więcej Shale is the most common source rock for hydrocarbons (natural gas and petroleum). The lack of coarse sediments in most shale beds reflects the absence of strong currents in the waters of the depositional basin. These might have oxygenated the waters and … Zobacz więcej • Bakken Formation – Geological rock formation known for crude oil production • Barnett Shale – Geological formation in Texas, United States • Bearpaw Formation – Geologic formation in North America Zobacz więcej Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the … Zobacz więcej The fine particles that compose shale can remain suspended in water long after the larger particles of sand have been deposited. As … Zobacz więcej Before the mid-19th century, the terms slate, shale and schist were not sharply distinguished.
