Formation

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.

Tephrite 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.
