Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

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.
Nephelinite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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