5 Formation

5.1 Formation

Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

Picrite 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 Picrite and Mugearite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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. You can check out Picrite vs Mugearite information and Picrite vs Mugearite characteristics in the upcoming sections.

More about Picrite and Mugearite

Here you can know more about Picrite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Mugearite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Picrite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Picrite is Rough and Shiny and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Picrite vs Mugearite. The hardness of Picrite is 6.8 and that of Mugearite is 6. The types of Picrite are Oceanite 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 Picrite is white, greenish white or grey while that of Mugearite is white to grey. The specific heat capacity of Picrite is 0.88 kJ/Kg K and that of Mugearite 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.Picrite is heat resistant whereas Mugearite is heat resistant, pressure resistant, wear resistant.
