Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava

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

Formation

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

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.
