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.

More about Anthracite and Shoshonite
Here you can know more about Anthracite and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Shoshonite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Shoshonite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Shoshonite is available in brown- black, dark brown colors. Appearance of Anthracite is Veined or Pebbled and that of Shoshonite is Dull. Properties of rock is another aspect for Anthracite vs Shoshonite. The hardness of Anthracite is 1-1.5 and that of Shoshonite is 6. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Shoshonite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Shoshonite is white to grey.
