Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
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 Tonalite and Suevite Properties
Know all about Tonalite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Tonalite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Tonalite is Phaneritic whereas that of Suevite is Earthy. Tonalite appears Banded and Foilated and Suevite appears Banded. The luster of Tonalite is subvitreous to dull while that of Suevite is earthy. Tonalite is available in black, brown, light to dark grey, white colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Tonalite are cemetery markers, creating artwork and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
