5.1 Formation
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.
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.

Pumice 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 Pumice and Anorthosite Reserves. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Pumice vs Anorthosite information and Pumice vs Anorthosite characteristics in the upcoming sections.

Pumice 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. Pumice vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pumice and Properties of Anorthosite. Learn more about Pumice vs Anorthosite in the next section. The interior uses of Pumice include Decorative aggregates, Flooring, 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 Pumice and Anorthosite, they have various applications in construction industry. The uses of Pumice in construction industry include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.

More about Pumice and Anorthosite

Here you can know more about Pumice and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Anorthosite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Pumice is Vesicular and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Pumice vs Anorthosite. The hardness of Pumice is 6 and that of Anorthosite is 5-6. The types of Pumice are Scoria 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 Pumice and Anorthosite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 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.Pumice is impact resistant, pressure resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
