5 Formation

5.1 Formation

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

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.

Skarn vs Mugearite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Skarn and Mugearite Reserves. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.

More about Skarn and Mugearite

Here you can know more about Skarn and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Mugearite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all . When we have to compare Skarn vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Skarn is Dull and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Skarn vs Mugearite. The hardness of Skarn is 6.5 and that of Mugearite is 6. The types of Skarn are Endoskarns whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Skarn is light to dark brown while that of Mugearite is white to grey. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Mugearite is 0.84 kJ/Kg K.
