Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.

All about Basanite and Adamellite Properties
Know all about Basanite and Adamellite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Adamellite belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Adamellite is Porphyritic. Basanite appears Glassy or Pearly and Adamellite appears Veined or Pebbled. The luster of Basanite is waxy and dull while that of Adamellite is dull to grainy with sporadic parts pearly and vitreous. Basanite is available in black, brown, green, grey, red, white colors whereas Adamellite is available in black, grey, orange, 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 Adamellite are curling, gemstone, laboratory bench tops, tombstones.
