Definition
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
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 Trachyte and Suevite Properties
Know all about Trachyte and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Trachyte belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Trachyte is Aphanitic to Porphyritic whereas that of Suevite is Earthy. Trachyte appears Banded and Suevite appears Banded. The luster of Trachyte is metallic while that of Suevite is earthy. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Trachyte are cemetery markers, creating artwork and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
