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
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic

Etymology
From the place of origin called Shoshone riverin Wyoming
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

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.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Shoshonite vs Phonolite 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. Shoshonite vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shoshonite and Properties of Phonolite. Learn more about Shoshonite vs Phonolite in the next section. The interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Shoshonite and Phonolite, they have various applications in construction industry. The uses of Shoshonite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.
More about Shoshonite and Phonolite
Here you can know more about Shoshonite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Phonolite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Phonolite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Shoshonite is Dull and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Shoshonite vs Phonolite. The hardness of Shoshonite is 6 and that of Phonolite is 5.5-6. The types of Shoshonite are Not Available whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite is white to grey while that of Phonolite is white. The specific heat capacity of Shoshonite is Not Available and that of Phonolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shoshonite is heat resistant, pressure resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
