Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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.
