Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Suevite and Shonkinite Properties
Know all about Suevite and Shonkinite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Shonkinite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Shonkinite is Earthy. Suevite appears Banded and Shonkinite appears Banded and Foilated. The luster of Suevite is earthy while that of Shonkinite is subvitreous to dull. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Shonkinite are cemetery markers, creating artwork.
