Definition

Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.

Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
