Definition

Trachyandesite is an extrusive igneous rock.

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

Formation

Trachyandesite 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.
