Archaeological Significance
Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
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.

Mugearite vs Anorthosite 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. Mugearite vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Anorthosite. Learn more about Mugearite vs Anorthosite in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Mugearite and Anorthosite, they have various applications in construction industry. The uses of Mugearite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Mugearite and Anorthosite
Here you can know more about Mugearite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Anorthosite consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Mugearite is available in black, brown, light to dark grey colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Mugearite is Dull and Soft and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mugearite vs Anorthosite. The hardness of Mugearite is 6 and that of Anorthosite is 5-6. The types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite 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 Mugearite is white to grey while that of Anorthosite is white. The specific heat capacity of Mugearite is 0.84 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.Mugearite is heat resistant, pressure resistant, wear resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
