WebFigure 3b-4 shows a coronitic eclogite originated from a cumulitic gabbro. In this metamorphic rock the igneous olivines have been pseudomorphosed by a garnet corona (Gr) surrounding an aggregate of omphacite (Omp) and amphibole (Amp), whereas the igneous plagioclases have been pseudomorphosed by an aggregate of albite (Ab) and … WebNov 1, 2024 · Eclogites are witnesses of geodynamic processes that are commonly related to subduction of oceanic crust. Information on the part of these processes that refers to the burial of this rock type is rarely published but stored in the eclogitic garnet core and inclusions therein.
Webeclogite, any member of a small group of igneous and metamorphic rocks whose composition is similar to that of basalt. Eclogites consist primarily of green pyroxene (omphacite) and red garnet (pyrope), with small amounts of various other stable … WebEclogite is a non-foliated, predominantly bi-mineralic metamorphic rock consisting of garnet and pyroxene. It is easily identifiable by its relatively large, red garnet crystals set in a matrix of fine-grained, light-green pyroxene. It may also have smaller amounts of accessory minerals like kyanite, rutile, and quartz.
WebThe name is derived from the Greek description ekloge, with the suffix “-ite,” meaning “chosen rock.” The name “eclogite” was created before Scottish geologist Charles Lyell in 1833 coined the term “metamorphic rocks.” Eclogite has been synonymous with eclogite facies, since Finnish geologist Pentti Eskola introduced the concept of WebAug 31, 2024 · The seismic features derived from the Flem eclogite can thus be used to distinguish olivine-rich eclogite from other common rock types (especially gabbro) in the deep continental crust or...
WebAug 1, 2001 · When Haüy created the name “eclogite”, meaning select or chosen rock, in 1822, he was impressed by the beauty of the rock and by the peculiarity of its mineral association. He certainly did not realise that this rock would prove to be a “chosen” rock in more than one sense.
