Shale is an abundant, fine-grained, clastic sedimentary rock. The rock forms when silt and clay-sized mineral particles compress. Its composition and properties place the rock in the “mudstones category.”

Most shales are formed in marine environments, with groundwater highly saline. Shale acts as a semipermeable membrane, allowing water to pass through and retaining dissolved stains.

Some shales are rich in unoxidized carbon. These are known as black shales, and some of them may also contain heavy metals like uranium, vanadium, zinc, and molybdenum. A few shales also contain fossils, animal tracks, burrows, or raindrop impressions.
