The ancient sedimentary rock record is composed of about 70 percent mudstones (which contain about 50 percent clay-sized fragments) and shales (which are coarser than mudstones but which may contain clay-sized particles) (Blatt and others, 1980).Scanning electron micrographs of several shales indicate that the shale rocks are comprised of stacks of locally aligned clay platelets (Hornby et al., 1994; Sayers & den Boer, 2019). The stacks are often called domains (Aylmore & Quirk, 1960 ), and this local alignment is a key source of shale anisotropy (Sayers & den Boer, 2019 ).Aug 2, 2020 · Shale consists of at least 30 percent clay, with varying amounts of quartz, feldspar, carbonates, iron oxides, and organic matter. Oil shale or bituminous also contains kerogen, a mixture of hydrocarbons from deceased plants and animals. Shale is classified based on its mineral content. As a result, clay shale and mixed shale have the best oil content and mobility. Clay shale with a TOC greater than 3% has a high hydrocarbon content, but high-polar hydrocarbons may lead to pore-throat blockage and poor mobility. Felsic shale with a TOC less than 1% has a low hydrocarbon content and small quantities of movable oil.The gas in the Marcellus Shale is a result of its contained organic content. Logic therefore suggests that rocks that contain higher amounts of organic material have a greater ability to generate natural gas.
