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
Aplite is a fine-grained granite composed mainly of feldspar and quartz

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.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Shoshonite vs Aplite 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 Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shoshonite and Properties of Aplite. Learn more about Shoshonite vs Aplite in the next section. The interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Shoshonite and Aplite, 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 Aplite include As dimension stone.
More about Shoshonite and Aplite
Here you can know more about Shoshonite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Aplite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Aplite, 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, Aplite is available in black, grey, orange, pink, white colors. Appearance of Shoshonite is Dull and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Shoshonite vs Aplite. The hardness of Shoshonite is 6 and that of Aplite is 6.5. The types of Shoshonite are Not Available whereas types of Aplite are Not Available. 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 Aplite is white. The specific heat capacity of Shoshonite is Not Available and that of Aplite is 0.79 kJ/Kg K. 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 Aplite is heat resistant, wear resistant.
