Definition

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

Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture

Formation

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.

Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.
