Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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.
