Where is shale formed.

What is Shale. Shale is a type of clastic sedimentary rock that contains mud, flakes of clay minerals and a trace amount of other minerals. More precisely, shale is a thin layer of mudstone. Mudstones have several parallel layers of material. Shale primarily contains mud and clay. But there can be trace amounts of quartz, and calcite.
