Definition

Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine

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

Formation

Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.
