Definition
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Mugearite and Basanite Properties
Know all about Mugearite and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Mugearite and Basanite belong to Igneous Rocks.Texture of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Basanite is Aphanitic to Porphyritic. Mugearite appears Dull and Soft and Basanite appears Glassy or Pearly. The luster of Mugearite is not available while that of Basanite is waxy and dull. Mugearite is available in black, brown, light to dark grey colors whereas Basanite is available in black, brown, green, grey, red, white colors. The commercial uses of Mugearite are creating artwork and that 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.
