Chalk vs Amphibolite

Chalk vs Amphibolite 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 Amphibolite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. 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 Amphibolite information and Chalk vs Amphibolite characteristics in the upcoming sections.

Chalk vs Amphibolite 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 Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Amphibolite. Learn more about Chalk vs Amphibolite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Chalk and Amphibolite, 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 Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.

More about Chalk and Amphibolite

Here you can know more about Chalk and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Amphibolite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Chalk is Soft and that of Amphibolite is Foliated. Properties of rock is another aspect for Chalk vs Amphibolite. The hardness of Chalk is 1 and that of Amphibolite is 6-7. The types of Chalk are Chalk Marl and Marl whereas types of Amphibolite are Hornblendite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk is white while that of Amphibolite is white to grey. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Amphibolite 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 Amphibolite is heat resistant, pressure resistant, wear resistant.
