Sandstone is a clastic sedimentary rock comprised of sand-sized particles about .1 to .2 mm in size. It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. The sand grains are most often made of quartz, cemented together by calcite or silica.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. A map showing the net feet of organic-rich shale in the Marcellus Formation can be viewed on this page. Shale gas is natural gas found in shale deposits, where it is trapped in microscopic or submicroscopic pores.

Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate.Mudstone.

Shale is an abundant, fine-grained, clastic sedimentary rock. The rock forms when silt and clay-sized mineral particles compress. Its composition and properties place the rock in the “mudstones category.”. …Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate. shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. 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 limestone.Description: The New Albany Shale is composed of brownish-black carbon-rich shale, greenish- gray shale, and minor amounts of dolostone and dolomitic quartz sandstone (Lineback, 1968, 1970; Hasenmueller, 1986).

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.To simplify the description of a shale reservoir that has irregularly shaped matrix and microfractures, it is assumed that the matrix element is a sphere with radius R m; each matrix element is composed of organics and clay grains, and gas flow in matrix is only diffusion (shown in Fig. 1.23).
