Eclogites and Eclogites: Their Differences and Similarities

Geological Society of America Bulletin, 1965
Eclogites are divisible into three groups based on mode of occurrence: Group A, inclusions in kimberlites, basalts, or layers in ultramafic rocks; Group B, bands or lenses within migmatite gneissic terrains; Group C, bands or lenses within alpine-type metamorphic rocks.

Eclogites and eclogites in the Western Gneiss Region, Norwegian Caledonides

Lithos, 2000
The Western Gneiss Region WGR marks the outcrop of a composite terrane consisting of variably re-worked Proterozoic basement and parautochthonous or autochthonous cover units. The WGR exhibits a gross structural, petrographic . and thermobarometric zonation from southeast to northwest, reflecting an increasing intensity of Scandian late ...

Eclogites and eclogites: Implications for Archean tectonics

Geology
Abstract Eclogites are generally divided into two types, xenolithic (mantle) and orogenic (crustal). Xenolithic eclogites are late Archean (ca. 3.0−2.5 Ga) or Paleoproterozoic (ca. 2.1−1.7 Ga) in age and are widely interpreted to have been entrained in younger carbonated magmas as they rose through the lithospheric mantle roots of ...

Eclogites and the Eclogite Facies

1965
The rock name eclogite was coined by Hauy, a founder of crystallography, in 1822. Since the original definition of the name was vague, its meaning was gradually settled through its usage in later years. According to the generally established usage in the first half of the twentieth century, it means a rock mainly composed of omphacite and almandine ...

Tectonic significance of Alpine eclogites

Journal of Geodynamics, 1996
Abstract A review of P-T peaks and paths of eo- and meso-Alpine eclogite fades rocks occurring along the axial part of the Alpine chain shows that rocks re-equilibrated under high- and low- T (group-B and -C eclogites), are, respectively, hosted within a lower and an upper tectonic level of the Penninic nappe system.

Experimental studies on eclogites: The roles of magnetite and acmite in eclogitic assemblages

Chemical Geology, 1968
Abstract Reactions between albite, magnetite, garnet and clinopyroxene solid solutions have been studied at pressures up to 36 kbar at 1,100–1,300°C. A low pressure clinopyroxene + magnetite + plagioclase assemblage is replaced by a high pressure clinopyroxene + garnet + magnetite assemblage, or at intermediate pressures and higher temperatures, by a
