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.   
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Anorthosite vs Scoria 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 Scoria Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria information and Anorthosite vs Scoria characteristics in the upcoming sections.

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

More about Anorthosite and Scoria

Here you can know more about Anorthosite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Scoria consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Anorthosite vs Scoria. Hardness of Anorthosite and Scoria is 5-6. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Scoria is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Scoria 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
