Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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