Abstract The soles of ophiolites preserve slices of oceanic crust metamorphosed to amphibolite‐ to granulite‐facies conditions beneath heavily deformed mantle peridotites, providing key records of fluid and mass transfer across nascent subduction interfaces.

Two hundred years eclogites and one hundred years of eclogite discussion
The first significant publication on eclogites (Escola, 1921) marked the start of the longest-discussed problem in petrology – the genesis and the place of eclogite formation and eclogite facies on the Earth. The mineral paragenesis of garnet, omphacite, rutile with rare inclusion of microdiamond in garnet requires conditions of T=800–1000 °C and P=0 ...

AN EXPERIMENTAL STUDY OF THE BASALT-ECLOGITE TRANSITION [PDF]
The basalt-eclogite transition has been investigated experimentally using natural basalt as the starting material. Temperature interval investigated in this work was not so wide (from the solidus of the basalt to 850°C) that the stability lines ...

Eclogite, one of the important lithologies in the main hole of the Chinese Continental Scientific Drilling (CCSD) Project, exists above the depth of 3 245 m and has distinctive responses of gamma-ray, compensating density and neutron well-logging, and so

A petrological and mineralogical study of peridotite and eclogite xenoliths from certain kimberlite pipes [PDF]
Kimberlite, an ultrabasic diamond-bearing hypabyssal rock-type which has its origin in the Earth's upper mantle, characteristically contains rare, well-rounded xenoliths of peridotite and eclogite.

The Theodul-Glacier-Unit (TGU) is a 100 m thick and 2 km long slab of pre-Alpine schist, gneiss and mafic rocks tectonically emplaced in the eclogite-facies Zermatt-Saas meta-ophiolite nappe (ZSU).

The role of eclogite in the mantle heterogeneity at Cape Verde
The Cape Verde hotspot, like many other Ocean Island Basalt provinces, demonstrates isotopic heterogeneity on a 100–200 km scale. The heterogeneity is represented by the appearance of an EM1-like component at several of the southern islands and with a ...

The rarity of natural rocks that specifically record the physicochemical conditions of the subduction interface strongly hampers pertinent studies on metamorphic trajectories of high‐pressure (HP) rocks and related fluid–rock interactions.

The beauty of an eclogite is something to behold: any petrologist marvels in the combination of red garnet and green omphacite that are the main mineral constituents of the rock. But besides their stunning appearance, there is much more to eclogites: fundamental concepts in metamorphic petrology and geodynamics were developed based on scientific ...
