Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Basanite and Cataclasite Properties
Know all about Basanite and Cataclasite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Cataclasite belongs to Metamorphic Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Cataclasite is Clastic. Basanite appears Glassy or Pearly and Cataclasite appears Dull and Banded. The luster of Basanite is waxy and dull while that of Cataclasite is vitreous. Basanite is available in black, brown, green, grey, red, white colors whereas Cataclasite is available in brown, green, white, yellow 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 Cataclasite are commemorative tablets, creating artwork.
