Definition

Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar

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

Formation

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

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.
