Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar

Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Archaeological Significance
Formation
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

More about Arkose and Vogesite
Here you can know more about Arkose and Vogesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Vogesite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Arkose vs Vogesite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Arkose is Rough and Dull and that of Vogesite is Dull, Banded and Foilated. Properties of rock is another aspect for Arkose vs Vogesite. The hardness of Arkose is 6-7 and that of Vogesite is 5-6. The types of Arkose are Arkose 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 Arkose and Vogesite is white. The specific heat capacity of Arkose is 0.78 kJ/Kg K and that of Vogesite 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.Arkose is heat resistant, impact resistant, pressure resistant whereas Vogesite is heat resistant, impact resistant.
