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
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

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.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Shoshonite and Hawaiite Properties
Know all about Shoshonite and Hawaiite properties here. All properties of rocks are important as they define the type of rock and its application. Shoshonite and Hawaiite belong to Igneous Rocks.Texture of Shoshonite is Porphyritic whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Shoshonite appears Dull and Hawaiite appears Dull and Soft. The luster of Shoshonite is dull while that of Hawaiite is not available. Shoshonite is available in brown- black, dark brown colors whereas Hawaiite is available in black, brown, light to dark grey colors. The commercial uses of Shoshonite are cemetery markers, creating artwork and that of Hawaiite are creating artwork, sea defence.
