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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Soapstone vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Soapstone and Properties of Quartzite. Learn more about Soapstone vs Quartzite in the next section. The interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Soapstone and Quartzite, they have various applications in construction industry. The uses of Soapstone in construction industry include Manufacture of magnesium and dolomite refractories and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Soapstone and Quartzite
Here you can know more about Soapstone and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Quartzite 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 Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Quartzite is Lustrous. Properties of rock is another aspect for Soapstone vs Quartzite. The hardness of Soapstone is 1 and that of Quartzite is 6-7. The types of Soapstone are Not Available whereas types of Quartzite are Not Available. 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 Quartzite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
