Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
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
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
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.

Arkose 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. Arkose vs Shoshonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Shoshonite. Learn more about Arkose vs Shoshonite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Arkose and Shoshonite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Shoshonite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Arkose and Shoshonite
Here you can know more about Arkose and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Shoshonite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Arkose vs Shoshonite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Shoshonite is available in brown- black, dark brown colors. Appearance of Arkose is Rough and Dull and that of Shoshonite is Dull. Properties of rock is another aspect for Arkose vs Shoshonite. The hardness of Arkose is 6-7 and that of Shoshonite is 6. The types of Arkose are Not Available 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 Arkose is white while that of Shoshonite is white to grey. The specific heat capacity of Arkose is Not Available and that of Shoshonite is Not Available.
