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.Shale is a tightly packed sedimentary rock. The shale is very porous, but it is not very permeable. This allows the shale to hold a lot of oil/natural gas but makes it difficult to remove those energy sources. Recent technologies have made it possible to extract the oil and natural gas trapped in deep shale formations.

Although this is not a complete list, it is a good introduction to depositional environments. Continental. Transitional.Shale split into thin flakes along the bedding fissility. Field of view is 15 cm wide. Although slate can be split more perfectly than shale, it generally requires a hammer and a chisel (Figure 6). Unlike shale, the tiles and flakes produced by splitting slate have sharp edges, especially when the rock has been newly quarried.Feb 19, 2021 · Sedimentary rock often contains fossils because it is formed differently. It consists of sandstone, limestone, or shale that was once mud or sand in which the bodies of dead animals settled. The temperatures and pressures that create sedimentary rock are much lower and don’t destroy fossil remains. For fossils to form, the parts of a dead ... The finer‐grained clastic sedimentary rocks are called shale, siltstone, and mudstone. Shale is a smooth, thinly layered rock that is made up of fine‐grained silt and clay particles.
