Chalk vs Sovite 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 Chalk and Sovite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock. 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 Chalk vs Sovite information and Chalk vs Sovite characteristics in the upcoming sections.

Chalk vs Sovite 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. Chalk vs Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Sovite. Learn more about Chalk vs Sovite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Chalk and Sovite, they have various applications in construction industry. The uses of Chalk in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium and that of Sovite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Unknown, Unknown.

More about Chalk and Sovite

Here you can know more about Chalk and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Sovite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Sovite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Sovite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Chalk is Soft and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Chalk vs Sovite. The hardness of Chalk is 1 and that of Sovite is 3. The types of Chalk are Not Available whereas types of Sovite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Sovite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Sovite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Chalk is heat resistant whereas Sovite is heat resistant, pressure resistant.
