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.
Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Anorthosite vs Kenyte 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 Kenyte Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix. 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 Kenyte information and Anorthosite vs Kenyte characteristics in the upcoming sections.

Anorthosite vs Kenyte 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 Kenyte characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Kenyte. Learn more about Anorthosite vs Kenyte in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Anorthosite and Kenyte, 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 Kenyte include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.

More about Anorthosite and Kenyte

Here you can know more about Anorthosite and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Kenyte consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Kenyte, 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, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Anorthosite vs Kenyte. The hardness of Anorthosite is 5-6 and that of Kenyte is 5.5-6. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Kenyte are Foidolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite is white while that of Kenyte is white, greenish white or grey. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Kenyte 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 Kenyte is heat resistant, impact resistant, wear resistant.
