Definition
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Archaeological Significance
Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
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 Mylonite and Pantellerite
Here you can know more about Mylonite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Pantellerite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts 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 Mylonite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Mylonite vs Pantellerite. The hardness of Mylonite is 3-4 and that of Pantellerite is 6-7. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite is white while that of Pantellerite is .
