What is a shale rock.

Shale is a fine-grained sedimentary rock that forms when silt and clay-size mineral particles are compacted, and it is easily broken into thin, parallel layers. Black shale contains organic material that can generate oil and natural gas, which is trapped within the rock's pores. Oct 9, 2019 · Shale can be fairly hard if it has a silica cement, making it closer to chert. Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate.
