Definition
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
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.
