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

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