Definition
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Borolanites 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 Borolanite and Suevite Properties
Know all about Borolanite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Borolanite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Borolanite is Granular whereas that of Suevite is Earthy. Borolanite appears Banded and Foilated and Suevite appears Banded. The luster of Borolanite is greasy to dull while that of Suevite is earthy. Borolanite 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 Borolanite are cemetery markers and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
