Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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.
