Definition
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
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Formation
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.
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.

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