Definition
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar
  
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Formation
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
  
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Minette and Basanite Properties
Know all about Minette and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Minette and Basanite belong to Igneous Rocks.Texture of Minette is Porphyritic whereas that of Basanite is Aphanitic to Porphyritic. Minette appears Dull, Banded and Foilated and Basanite appears Glassy or Pearly. The luster of Minette is subvitreous to dull while that of Basanite is waxy and dull. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Basanite is available in black, brown, green, grey, red, white colors. The commercial uses of Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) 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.
