Definition

Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine

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

Formation

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

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.
