What makes up shale
Rock Composition. Shale and other mudstones are primarily composed of clay minerals. The major clay minerals include kaolinite, illite, and montmorillonite. A typical shale is made of clay minerals (58%), quartz (28%), feldspar (6%), carbonate minerals (5%), and iron oxides (2%).This paper provides a critical review of the observed, phenomenological behavior of shale softening, and summarizes the currently recognized potential or hypothesized underlying mechanisms. The former includes: (1) reduction in fracture conductivity and hence the rate of gas production; (2) degradation of mechanical properties and reservoir ...What is the name of the rock in the above image?

The shale is made of alternating fine-grained layers of siliceous mudstone (compressed, hardened mud originally made of ground-up silicate rock) and calcisiltite originally animal shells. The calcisiltite layers contain relatively unremarkable shells and occasional non- biomineralized fossils (such as priapulid tubes). Natural gas is a fossil fuel energy source. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH 4 ). Natural gas also contains smaller amounts of natural gas liquids (NGLs, which are also hydrocarbon gas liquids ), and nonhydrocarbon gases ...Use a razor to shave the top line of the mustache following the curve of your mouth.

Oil shale is a form of sedimentary rock that contains kerogen, which is released as a petroleum-like liquid when the rock is heated. Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon.
