5 Formation

5.1 Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
