Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
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
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

More about Metapelite and Vogesite
Here you can know more about Metapelite and Vogesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Vogesite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Vogesite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Metapelite is Banded and that of Vogesite is Dull, Banded and Foilated. Properties of rock is another aspect for Metapelite vs Vogesite. Hardness of Metapelite and Vogesite is 5-6. The types of Metapelite are Metamorphic rock 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 Metapelite is while that of Vogesite is white. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Vogesite is heat resistant, impact resistant.
