Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
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 Arkose and Suevite Properties
Know all about Arkose and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Arkose belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Arkose is Clastic whereas that of Suevite is Earthy. Arkose appears Rough and Dull and Suevite appears Banded. The luster of Arkose is dull while that of Suevite is earthy. Arkose is available in reddish brown colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
