Chalk vs Schist

Chalk vs Schist 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 Schist Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Schist information and Chalk vs Schist characteristics in the upcoming sections.

Chalk vs Schist 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 Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Schist. Learn more about Chalk vs Schist in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Chalk and Schist, 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 Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.
