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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
