Shale is a fine-grained, clastic sedimentary rock, formed from mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers (laminae) less than one centimeter in thickness.

Mudstone - hardened mud; a mix of silt and clay sized particles. The difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. The terms shale and claystone are sometimes used interchangeably.

Apr 25, 2017 · Slate is one stage in the metamorphosis of shale, a sedimentary rock, to gneiss, a metamorphic rock. Slate can also form from volcanic rock. In slate, the heated and compacted minerals slowly flow and align themselves perpendicular to the axis of compression, to create "cleavage," which is the tendency of the rock to break along straight lines.

Clay, soil particles the diameters of which are less than 0.005 millimeter; also a rock that is composed essentially of clay particles. Rock in this sense includes soils, ceramic clays, clay shales, mudstones, glacial clays, and deep-sea clays. Clay materials are plastic when wet and coherent when dry.According to Plexaderm, a “shale mineral” flattens the skin and visibly reduces under-eye bags. This is a reference to silicate minerals obtained from shale clay. We mentioned this ingredient earlier but it’s worth returning to — magnesium aluminum silicate. It is the key thickening agent (along with cellulose gum) in Plexaderm.However, if the protolith is shale, a muscovite-biotite schist, which is not green, will form instead. If it can be determined that a muscovite-biotite schist formed at around 350ºC temperature and 400 MPa pressure, it can be stated that the rock formed in the greenschist facies, even though the rock is not itself a greenschist.The Wufeng-Longmaxi marine shale is a hot spot of shale gas exploitation in China.

Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth. Shales are often found with layers of sandstone or

Additionally, if clay minerals form along bedding planes, they can absorb water and become slick. When a bedding plane of shale (clay and silt) becomes saturated, it can lower the shear strength of the rock mass and cause a landslide, such as at the 1925 Gros Ventre, Wyoming rock slide.

The quartz content accounts for 17–73 wt% in the marine LMX shale and 7–58 wt% in the continental ZLJ shale.
