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.

Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

All about Suevite and Dacite Properties

Know all about Suevite and Dacite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Dacite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Dacite is Aphanitic to Porphyritic. Suevite appears Banded and Dacite appears Vesicular. The luster of Suevite is earthy while that of Dacite is subvitreous to dull. Suevite is available in black, brown, green, grey, pink colors whereas Dacite is available in bluish - grey, brown, grey, 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 Dacite are commemorative tablets, creating artwork.
