Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
