Formation

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

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 Tonalite and Mugearite

Here you can know more about Tonalite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Mugearite consists of mineral content and compound content. The mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon 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 Tonalite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Tonalite is available in black, brown, light to dark grey, white colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Tonalite is Banded and Foilated and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Tonalite vs Mugearite. The hardness of Tonalite is 6-7 and that of Mugearite is 6. The types of Tonalite are Dacite 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 Tonalite is bluish black while that of Mugearite is white to grey. The specific heat capacity of Tonalite is 0.92 kJ/Kg K and that of Mugearite is 0.84 kJ/Kg K.
