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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Anorthosite vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Talc carbonate. Learn more about Anorthosite vs Talc carbonate in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Anorthosite and Talc carbonate, 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 Talc carbonate include Source of calcium.
More about Anorthosite and Talc carbonate
Here you can know more about Anorthosite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Talc carbonate consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Talc carbonate is Soft. Properties of rock is another aspect for Anorthosite vs Talc carbonate. The hardness of Anorthosite is 5-6 and that of Talc carbonate is 1-2. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Talc carbonate is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
