Definition
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
Shoshonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Anthracite and Shoshonite Properties
Know all about Anthracite and Shoshonite properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite belongs to Metamorphic Rocks while Shoshonite belongs to Igneous Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Shoshonite is Porphyritic. Anthracite appears Veined or Pebbled and Shoshonite appears Dull. The luster of Anthracite is shiny while that of Shoshonite is dull. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas Shoshonite is available in brown- black, dark brown colors. The commercial uses of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry and that of Shoshonite are cemetery markers, creating artwork.
