Definition
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar
  
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
  
Epidosite 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 vs Epidosite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Vogesite vs Epidosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Vogesite and Properties of Epidosite. Learn more about Vogesite vs Epidosite in the next section. The interior uses of Vogesite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration. Due to some exceptional properties of Vogesite and Epidosite, they have various applications in construction industry. The uses of Vogesite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Epidosite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Vogesite and Epidosite
Here you can know more about Vogesite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Vogesite and Epidosite consists of mineral content and compound content. The mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Vogesite vs Epidosite, 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, Epidosite is available in black, brown, light to dark grey colors. Appearance of Vogesite is Dull, Banded and Foilated and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Vogesite vs Epidosite. The hardness of Vogesite is 5-6 and that of Epidosite is 6. The types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Epidosite 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 Vogesite is white while that of Epidosite is white to grey. The specific heat capacity of Vogesite is Not Available and that of Epidosite is Not Available. 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 Epidosite is heat resistant, pressure resistant, wear resistant.
