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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Mugearite vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Talc carbonate. Learn more about Mugearite vs Talc carbonate in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mugearite and Talc carbonate, 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 Talc carbonate include Source of calcium.
More about Mugearite and Talc carbonate
Here you can know more about Mugearite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Talc carbonate consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Igneous Rocks. When we have to compare Mugearite vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Mugearite is Dull and Soft and that of Talc carbonate is Soft. Properties of rock is another aspect for Mugearite vs Talc carbonate. The hardness of Mugearite is 6 and that of Talc carbonate is 1-2. 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 Talc carbonate 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 Talc carbonate is white. The specific heat capacity of Mugearite is 0.84 kJ/Kg K and that of Talc carbonate 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 Talc carbonate is heat resistant, wear resistant.
