How shale rock is formed?

Answer 1

Compaction is the process of pore space reduction due to pressure exerted, normally by overburden weight. Shale would be produced by the process of lithification, which includes the individual steps of compaction and cementation of particles of sediment. Cementation occurs as mineral crystals precipitate from the water removed by compaction, binding the sedimentary particles together into rock.

Answer 2

The mineral grains in the mud or silt can become cemented together by precipitating minerals which are formed as the fluid escapes, in a process called cementation. Once the particles are cemented together, sedimentary rock is formed.

Answer 3

This is known broadly as lithification. It involves the processes of compaction and cementation. However in this specific question you only refer to the compaction process (the act of removing water and air or more technically reducing the void ratio or porosity),

Answer 4

Shale is the compressed result of very fine eroded particles carried by water and deposited in calm marine conditions as sediment. This is typical of shallow water deposition with minimal current or tidal activity. The exceptionally small particles in shale are ideal for preserving the surface details of fossils.
