Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
  
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
  
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 Eclogite and Pantellerite
Here you can know more about Eclogite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Pantellerite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite 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 Eclogite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Eclogite vs Pantellerite. The hardness of Eclogite is 3.5-4 and that of Pantellerite is 6-7. The types of Eclogite are Not Available 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 Eclogite is white while that of Pantellerite is unknown. The specific heat capacity of Eclogite is Not Available and that of Pantellerite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Eclogite is heat resistant whereas Pantellerite is heat resistant.
