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

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

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