Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

All about Basanite and Scoria Properties
Know all about Basanite and Scoria properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Scoria belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Scoria is Vesicular. Basanite appears Glassy or Pearly and Scoria appears Glassy and Vesicular. The luster of Basanite is waxy and dull while that of Scoria is subvitreous to dull. Basanite is available in black, brown, green, grey, red, white colors whereas Scoria is available in black, brown, dark grey to black, red 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 Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills.
