1.1 Definition

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

Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

5 Formation

5.1 Formation

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

All about Basanite and Ignimbrite Properties

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