Shale definition

Shale means a fine-grained sedimentary rock formed by consolidation of clay- and silt-sized particles into thin, relatively impermeable layers. Shale can include relatively large amounts of organic material compared with other rock types and thus has the potential to become rich hydrocarbon source rock. Its fine grain size and lack of permeability can allow shale to form a good cap rock for hydrocarbon traps.
Shale means a fine-grained sedimentary rock that forms from the compaction of silt and clay commonly referred to as mud. “Sediment” means solid material settled from suspension in a liquid.
Shale means a laminated sedimentary rock composed chiefly of small particles of a clay grade.
