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. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Anorthosite vs Jadeitite 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 Jadeitite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Jadeitite. Learn more about Anorthosite vs Jadeitite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Anorthosite and Jadeitite, 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 Jadeitite include As dimension stone, Cutting tool, Knives.
More about Anorthosite and Jadeitite
Here you can know more about Anorthosite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Jadeitite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Jadeitite, 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, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Anorthosite vs Jadeitite. The hardness of Anorthosite is 5-6 and that of Jadeitite is 3-5. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Jadeitite are Not Available. 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 Jadeitite is white, greenish white or grey. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Jadeitite is 0.95 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 Jadeitite is heat resistant, water resistant.
