Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
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
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite vs Shoshonite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Basanite vs Shoshonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Shoshonite. Learn more about Basanite vs Shoshonite in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Basanite and Shoshonite, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Shoshonite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Basanite and Shoshonite
Here you can know more about Basanite and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Shoshonite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Shoshonite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Shoshonite is available in brown- black, dark brown colors. Appearance of Basanite is Glassy or Pearly and that of Shoshonite is Dull. Properties of rock is another aspect for Basanite vs Shoshonite. The hardness of Basanite is 7 and that of Shoshonite is 6. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite 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 Basanite is white while that of Shoshonite is white to grey. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Shoshonite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Shoshonite is heat resistant, pressure resistant.
