Definition
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Features
Has High structural resistance against erosion and climate, Very fine grained rock
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
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.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Mugearite vs Appinite 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 Appinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Appinite. Learn more about Mugearite vs Appinite in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Appinite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Mugearite and Appinite, 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 Appinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Mugearite and Appinite
Here you can know more about Mugearite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Appinite consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Appinite, 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, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Mugearite is Dull and Soft and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Mugearite vs Appinite. The hardness of Mugearite is 6 and that of Appinite 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 Appinite are Igneous rock. 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 Appinite is white. The specific heat capacity of Mugearite is 0.84 kJ/Kg K and that of Appinite 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 Appinite is heat resistant, impact resistant.
