Formation

Formation

Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
Trachyandesite 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.

More about Minette and Trachyandesite

Here you can know more about Minette and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Minette and Trachyandesite consists of mineral content and compound content. The mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Minette vs Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Minette is Dull, Banded and Foilated and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Minette vs Trachyandesite. The hardness of Minette is 5-6 and that of Trachyandesite is 4-5. The types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Trachyandesite are Basaltic Trachyandesite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Minette is white while that of Trachyandesite is light to dark brown. The specific heat capacity of Minette is 0.79 kJ/Kg K and that of Trachyandesite is 0.84 kJ/Kg K.
