Formation
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.
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.

Soapstone 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. Soapstone vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Soapstone and Properties of Aplite. Learn more about Soapstone vs Aplite in the next section. The interior uses of Soapstone include Bathrooms, 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 Soapstone and Aplite, they have various applications in construction industry. The uses of Soapstone in construction industry include Manufacture of magnesium and dolomite refractories and that of Aplite include As dimension stone.
More about Soapstone and Aplite
Here you can know more about Soapstone and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Aplite consists of mineral content and compound content. The mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz 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 Metamorphic Rocks. When we have to compare Soapstone vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Soapstone is available in black, black to grey, green, grey colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Soapstone vs Aplite. The hardness of Soapstone is 1 and that of Aplite is 6.5. The types of Soapstone are Metamorphic rock whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Soapstone is black while that of Aplite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K 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.Soapstone is heat resistant, pressure resistant whereas Aplite is heat resistant, wear resistant.
