Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

All about Basanite and Arkose Properties
Know all about Basanite and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Arkose belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Arkose is Clastic. Basanite appears Glassy or Pearly and Arkose appears Rough and Dull. The luster of Basanite is waxy and dull while that of Arkose is dull. Basanite is available in black, brown, green, grey, red, white colors whereas Arkose is available in reddish brown colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
