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

Formation
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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

All about Suevite and Chalk Properties
Know all about Suevite and Chalk properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Chalk belongs to Sedimentary Rocks.Texture of Suevite is Earthy whereas that of Chalk is Clastic or Non-Clastic. Suevite appears Banded and Chalk appears Soft. The luster of Suevite is earthy while that of Chalk is dull. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Chalk is available in grey, white, yellow colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Chalk are alumina refineries, creating artwork, drawing on blackboards, gymnasts, athletes and mountain climbers use for grip, in aquifers, paper industry, production of lime, raw material for manufacture of quicklime, slaked lime, soil conditioner, whiting, whiting material in toothpaste, paint and paper.
