Physical properties
Hardness of 6.5 to 7.5; distinct green and red coloration composed of green pyroxene and red garnet; submetallic to vitreous luster.
Formation & geological history
Forms by high-pressure and high-temperature metamorphism of basalt or gabbro during deep subduction processes.
Uses & applications
Primarily studied by geologists to understand subduction zone dynamics and mantle conditions; occasionally used as an ornamental stone.
Geological facts
Eclogite is a relatively rare rock type that provides direct evidence of tectonic processes occurring deep within the Earth's crust and mantle.
Field identification & locations
Easily identified by its striking green and red mineral assemblage. Commonly found in ultra-high-pressure metamorphic terranes globally.
