Eclogite and Enderbite
Definition
Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Enderbite rock is an igneous rock which belongs to the Charnockite rock series

Formation
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.
