Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

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.
