Formation

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

Hornblendite 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 Vogesite and Hornblendite

Here you can know more about Vogesite and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Vogesite and Hornblendite consists of mineral content and compound content. The mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Vogesite vs Hornblendite, the texture, color and appearance plays an important role in determining the type of rock. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Hornblendite is available in black, brown, green, grey colors. Appearance of Vogesite is Dull, Banded and Foilated and that of Hornblendite is Foliated. Properties of rock is another aspect for Vogesite vs Hornblendite. The hardness of Vogesite is 5-6 and that of Hornblendite is 6-7. The types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Vogesite is white while that of Hornblendite is white to grey. The specific heat capacity of Vogesite is 0.84 kJ/Kg K and that of Hornblendite is 0.84 kJ/Kg K.
