Chalk vs Shale

Chalk 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 Chalk and Shale Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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 Chalk vs Shale information and Chalk vs Shale characteristics in the upcoming sections.

Chalk 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. Chalk vs Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Shale. Learn more about Chalk vs Shale in the next section. The interior uses of Chalk include 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 Chalk and Shale, 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 Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Chalk and Shale

Here you can know more about Chalk and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Shale consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Chalk vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Chalk is Soft and that of Shale is Muddy. Properties of rock is another aspect for Chalk vs Shale. The hardness of Chalk is 1 and that of Shale is 3. The types of Chalk are Chalk Marl and Marl 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 Chalk and Shale is white. The specific heat capacity of Chalk is 0.90 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.Chalk is heat resistant whereas Shale is heat resistant, impact resistant.
