Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

High Fe content
Archaeological Significance
Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Pantellerite 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.

More about Migmatite and Pantellerite
Here you can know more about Migmatite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Pantellerite consists of mineral content and compound content. The mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Migmatite vs Pantellerite. The hardness of Migmatite is 5.5-6.5 and that of Pantellerite is 6-7. The types of Migmatite are Diatexites and Metatexites whereas types of Pantellerite are Pantelleritic Ignimbrite.
