Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick).

Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks:What does Shale look like?

Clay collected on the bottom of a lake or pond and compressed together, forming Shale. Shale beds are most common in the eastern region of Ohio. Best Locations: Shale ...Shale is essentially a rock type that is characterised by relatively lower permeability. The low permeability of the shale formation restricts the movement of oil and gas out of the formation. Due to this fact, traditional oil explorers refrain from drilling a vertical well as only low surface area is available for oil extraction, and shale is ...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.
