Definition

Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

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.

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
