Arkose and Diamictite
Definition
Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Formation
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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Arkose and Diamictite Properties
Know all about Arkose and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Arkose and Diamictite belong to Sedimentary Rocks.Texture of Arkose is Clastic whereas that of Diamictite is Clastic. Arkose appears Rough and Dull and Diamictite appears Banded. The luster of Arkose is dull while that of Diamictite is grainy, pearly and vitreous. Arkose is available in reddish brown colors whereas Diamictite is available in brown, buff colors. The commercial uses of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones and that of Diamictite are commemorative tablets, creating artwork, production of lime.
