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.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

Due to some exceptional properties of Mugearite and Itacolumite, 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 Itacolumite include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Mugearite and Itacolumite
Here you can know more about Mugearite and Itacolumite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Itacolumite consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Itacolumite, 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, Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Mugearite is Dull and Soft and that of Itacolumite is Rough. Properties of rock is another aspect for Mugearite vs Itacolumite. The hardness of Mugearite is 6 and that of Itacolumite is 6-7. 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 Itacolumite are Not Available. 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 Itacolumite is white. The specific heat capacity of Mugearite is 0.84 kJ/Kg K and that of Itacolumite is 0.92 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 Itacolumite is heat resistant, impact resistant, pressure resistant.
