Formation

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.   
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Soapstone vs Shale Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Soapstone and Shale Reserves. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Soapstone vs Shale information and Soapstone vs Shale characteristics in the upcoming sections.

Soapstone vs Shale 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 Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Soapstone and Properties of Shale. Learn more about Soapstone vs Shale in the next section. The interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Soapstone and Shale, they have various applications in construction industry. The uses of Soapstone in construction industry include Manufacture of magnesium and dolomite refractories and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Soapstone and Shale

Here you can know more about Soapstone and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Shale 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 Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Shale, 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, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Shale is Muddy. Properties of rock is another aspect for Soapstone vs Shale. The hardness of Soapstone is 1 and that of Shale is 3. The types of Soapstone are Not Available whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. 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 Shale is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Shale is 0.39 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 Shale is heat resistant, impact resistant.
