Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Variolites are a group of dark green basic igneous rocks which exhibit pale colored spots, or spherules, especially on weathered surfaces, that give them a pockmarked appearance

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.
Variolites are a group of dark green basic igneous rocks that exhibit pale colored spots on weathered surfaces that give them a pockmarked appearance.

All about Suevite and Variolite Properties
Know all about Suevite and Variolite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Variolite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Variolite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Suevite appears Banded and Variolite appears Dull and Soft. The luster of Suevite is earthy while that of Variolite is not available. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Variolite is available in black, brown, light to dark grey colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Variolite are cemetery markers, creating artwork.
