Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals.Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering.

Green to black fossiliferous shale forms massive to laminated beds 0.2–0.95 m thick and is rich in organic-matter and pyrite, hosting abundant ostracod microfossils and fish remains (Figs. 11 B, 12; Gallo et al., 2010).Last we have shale, which is composed of clay particles and has a finely layered or fissile appearance. This extremely mature sedimentary rock is made from the smallest particles that can be carried by wind or barely moving water and can be found thousands of miles away from the original source.Above the shale and limestone is a gravel deposit that was laid down not much over 100 thousand years ago, during the waning stages of Illinoian glaciation during the Ice Age. The line of contact between the gravel deposit above and the shale below thus represents a time gap of immense duration. Such a time-loss line is called an hiatus.fossiliferous shale-dark, smooth, and have plant fossils present. -Formed in muddy, fine-grained, depositional environment where plants were present. -low-energy . sandstone-formed from beach, river channel, lake, desert -characterized by grain size, roundness. cross-bedded sandstone ...The Marcellus shale play is the largest shale gas reservoir and gas producer in the United States.
