Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

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