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
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals

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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

More about Metapelite and Pegmatite
Here you can know more about Metapelite and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Pegmatite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Pegmatite, 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, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Metapelite is Banded and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Metapelite vs Pegmatite. The hardness of Metapelite is 5-6 and that of Pegmatite is 7. The types of Metapelite are Not Available whereas types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is unknown while that of Pegmatite is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Pegmatite is Not Available. 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 Pegmatite is heat resistant, impact resistant, pressure resistant.
