1.1 Definition
Rhyolite is a fine-grained igneous rock which is rich in silica
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

5 Formation
5.1 Formation
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.
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.
