Archaeological Significance
Formation
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 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.

More about Jadeitite and Anorthosite
Here you can know more about Jadeitite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Anorthosite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, green, grey, white colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Jadeitite is Rough and Dull and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Jadeitite vs Anorthosite. The hardness of Jadeitite is 3-5 and that of Anorthosite is 5-6. The types of Jadeitite are Metamorphic rock whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Anorthosite is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Anorthosite 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.Jadeitite is heat resistant, water resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
