Definition
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
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
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.
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.

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