Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

All about Basanite and Mudstone Properties
Know all about Basanite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Mudstone belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Mudstone is Clastic. Basanite appears Glassy or Pearly and Mudstone appears Rough and Dull. The luster of Basanite is waxy and dull while that of Mudstone is dull. Basanite is available in black, brown, green, grey, red, white colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, 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 Mudstone are creating artwork, pottery.
