Definition
An iron rich extrusive rock found as a member of the alkali basalt magma series
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
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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 Benmoreite and Shoshonite Properties
Know all about Benmoreite and Shoshonite properties here. All properties of rocks are important as they define the type of rock and its application. Benmoreite and Shoshonite belong to Igneous Rocks.Texture of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular whereas that of Shoshonite is Porphyritic. Benmoreite appears Rough and Dull and Shoshonite appears Dull. The luster of Benmoreite is earthy while that of Shoshonite is dull. Benmoreite is available in black, brown, light to dark grey colors whereas Shoshonite is available in brown- black, dark brown colors. The commercial uses of Benmoreite are commemorative tablets, creating artwork, curling and that of Shoshonite are cemetery markers, creating artwork.
