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
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

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

More about Vogesite and Metapelite
Here you can know more about Vogesite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Vogesite and Metapelite consists of mineral content and compound content. The mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Vogesite vs Metapelite, 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, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Vogesite is Dull, Banded and Foilated and that of Metapelite is Banded. Properties of rock is another aspect for Vogesite vs Metapelite. Hardness of Vogesite and Metapelite is 5-6. The types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Metapelite are Not Available. 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 Metapelite is unknown. The specific heat capacity of Vogesite is Not Available and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
