Definition
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
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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

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