Shale is a fine-grained, siliciclastic sedimentary rock. It is the # 1 most common sedimentary rock on Earth. Common colors of shale are black, gray, earth-tone reddish, and earth-tone greenish-gray."Fissile" means that the rock readily splits into thin pieces along the laminations. Uses of Shale Some shales have special properties that make them important resources. Black shales contain organic material that sometimes breaks down to form natural gas or oil.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.
