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

Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

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