Formation

Nephelinite 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.

More about Nephelinite and Mugearite

Here you can know more about Nephelinite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Nephelinite and Mugearite consists of mineral content and compound content. The mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase 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 Nephelinite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Nephelinite is available in black, brown, green, grey, white colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Nephelinite is Skeletal and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Nephelinite vs Mugearite. The hardness of Nephelinite is 6.5 and that of Mugearite is 6. The types of Nephelinite are Peralkaline Nephelinite 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 Nephelinite is white while that of Mugearite is white to grey. The specific heat capacity of Nephelinite 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.Nephelinite is heat resistant whereas Mugearite is heat resistant, pressure resistant, wear resistant.
