5 Formation

5.1 Formation

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.

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