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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

Mugearite vs Pegmatite 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 Pegmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Pegmatite. Learn more about Mugearite vs Pegmatite in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Pegmatite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Mugearite and Pegmatite, 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 Pegmatite include As dimension stone, Building houses or walls, Construction aggregate, For road aggregate, Landscaping.
More about Mugearite and Pegmatite
Here you can know more about Mugearite and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Pegmatite consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Pegmatite, 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, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Mugearite is Dull and Soft and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mugearite vs Pegmatite. The hardness of Mugearite is 6 and that of Pegmatite is 7. 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 Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. 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 Pegmatite is white. The specific heat capacity of Mugearite is 0.84 kJ/Kg K and that of Pegmatite is 0.79 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 Pegmatite is heat resistant, impact resistant, pressure resistant.
