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
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Shoshonite and Limestone Properties
Know all about Shoshonite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Shoshonite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Shoshonite is Porphyritic whereas that of Limestone is Clastic or Non-Clastic. Shoshonite appears Dull and Limestone appears Rough and Banded. The luster of Shoshonite is dull while that of Limestone is dull to pearly. Shoshonite is available in brown- black, dark brown colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Shoshonite are cemetery markers, creating artwork and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
