Features
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Available in Lots of Colors and Patterns, Generally rough to touch, Surfaces are often shiny
Archaeological Significance
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Vogesite and Scoria
Here you can know more about Vogesite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Vogesite and Scoria consists of mineral content and compound content. The mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Vogesite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Vogesite is Dull, Banded and Foilated and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Vogesite vs Scoria. Hardness of Vogesite and Scoria is 5-6. The types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Scoria are Basaltic Scoria and Andesitic Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Vogesite and Scoria is white. The specific heat capacity of Vogesite is 0.84 kJ/Kg K and that of Scoria 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.Vogesite is heat resistant, impact resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
