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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
