Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

All about Suevite and Adakite Properties
Know all about Suevite and Adakite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Adakite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Adakite is Porphyritic. Suevite appears Banded and Adakite appears Dull and Soft. The luster of Suevite is earthy while that of Adakite is grainy, pearly and vitreous. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Adakite is available in black, brown, light to dark grey colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Adakite are commemorative tablets, pottery, used in aquariums.
