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

More about Hornblendite and Vogesite
Here you can know more about Hornblendite and Vogesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Vogesite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Vogesite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Hornblendite is Foliated and that of Vogesite is Dull, Banded and Foilated. Properties of rock is another aspect for Hornblendite vs Vogesite. The hardness of Hornblendite is 6-7 and that of Vogesite is 5-6. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Vogesite is white. The specific heat capacity of Hornblendite is Not Available and that of Vogesite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Vogesite is heat resistant, impact resistant.
