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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Eclogite and Charnockite
Here you can know more about Eclogite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Charnockite 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 Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock.
