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.
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

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