5.1 Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Chalk vs Anorthosite 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 Anorthosite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Anorthosite is a granular igneous rock composed largely of labradorite or 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 Anorthosite information and Chalk vs Anorthosite characteristics in the upcoming sections.

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

More about Chalk and Anorthosite

Here you can know more about Chalk and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Anorthosite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Chalk is Soft and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Chalk vs Anorthosite. The hardness of Chalk is 1 and that of Anorthosite is 5-6. The types of Chalk are Not Available whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Anorthosite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Anorthosite 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 Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
