Formation

Formation

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.
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

Anorthosite vs Diatomite 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 Anorthosite and Diatomite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. 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 Anorthosite vs Diatomite information and Anorthosite vs Diatomite characteristics in the upcoming sections.

Anorthosite vs Diatomite 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. Anorthosite vs Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Diatomite. Learn more about Anorthosite vs Diatomite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Anorthosite and Diatomite, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Diatomite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium.

More about Anorthosite and Diatomite

Here you can know more about Anorthosite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Diatomite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Diatomite is Soft. Properties of rock is another aspect for Anorthosite vs Diatomite. The hardness of Anorthosite is 5-6 and that of Diatomite is 1. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Diatomite are Diatomite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Diatomite is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Diatomite is 0.90 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Diatomite is heat resistant.
