Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Basanite and Boninite Properties
Know all about Basanite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Boninite belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Boninite is Aphanitic to Porphyritic. Basanite appears Glassy or Pearly and Boninite appears Dull and Soft. The luster of Basanite is waxy and dull while that of Boninite is vitreous. Basanite is available in black, brown, green, grey, red, white colors whereas Boninite is available in bluish - grey, brown, green, grey 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 Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
