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