Origins. Eclogite typically results from high-pressure metamorphism of mafic igneous rock (typically basalt or gabbro) as it plunges into the mantle in a subduction zone.Such eclogites are generally formed from precursor mineral assemblages typical of blueschist metamorphism. Eclogite can also form from magmas that crystallize and cool within the mantle or lower crust …

Eclogite - an overview | ScienceDirect Topics

Abstract. Eclogite is an unusually dense metamorphic rock, typically of basaltic composition, that represents a recorder and/or driving force for planetary-scale processes and evolution. Eclogite-facies metamorphic conditions encompass a wide range of pressure–temperature space from deep crustal to mantle depths, reflecting tectonic setting.

Eclogite | SpringerLink

The rock name eclogite was first used by R. J. Haüy in 1822 for a "fancy rock" composed mainly of two minerals "diallage and garnet accompanied accidentally by kyanite, quartz, epidote, and lamellar amphibole." Later the name was applied to all granular rocks consisting essentially of greenish clinopyroxene and reddish garnet, with a possible admixture of several primary and …

 · Considering eclogite is recycled back into the Earth's mantle through slab subduction, the T of eclogite can be several hundred kelvins lower than the ambient mantle (e.g., Syracuse et al., 2010). We thus calculated velocity profiles along a colder 1000-K adiabat (Figure 6a), and the Vp and Vs of eclogite are elevated by ~2.0% and 2.8%.
