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.   
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

Anorthosite vs Trachyte 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 Trachyte Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar. 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 Trachyte information and Anorthosite vs Trachyte characteristics in the upcoming sections.

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

More about Anorthosite and Trachyte

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