Definition
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers  
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Chalk vs Boninite 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 Boninite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. 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 Boninite information and Chalk vs Boninite characteristics in the upcoming sections.

Chalk vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Boninite. Learn more about Chalk vs Boninite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Chalk and Boninite, 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 Boninite 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.

More about Chalk and Boninite

Here you can know more about Chalk and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Boninite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Chalk is Soft and that of Boninite is Dull and Soft. Properties of rock is another aspect for Chalk vs Boninite. The hardness of Chalk is 1 and that of Boninite is 7. The types of Chalk are Chalk Marl and Marl whereas types of Boninite are Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Boninite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Boninite is 0.84 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
