A metamorphic facies is a set of mineral assemblages in metamorphic rocks formed under similar pressures and temperatures. The assemblage is typical of what is formed in conditions corresponding to an area on the two dimensional graph of temperature vs. pressure (See diagram in Figure 1). Rocks which contain certain minerals can therefore be linked to certain tectonic settings, times and About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Read "The timing of eclogite facies metamorphism and migmatization in the Orlica–Śnieżnik complex, Bohemian Massif: constraints from a multimethod geochronological study, Journal of Metamorphic Geology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.

Eclogite is an extremely high-grade The eclogite on Hareidland, western Norway, is among the largest eclogite bodies yet described. It occurs as a sheet-like body folded together with the surrounding metasedimentary gneisses of the Petrogenesis of eclogites in high grade metamorphic gneisses, exemplified by the Hareidland eclogite, western Norway | SpringerLink eclogite facies metamorphism. The non-eclogitic units are characterized by strong orogen-parallel ductile deformation and associated thinning. This deformation overprints the formation of at least two large-scale nappes. The P-Tpaths of the higher-grade metamorphic units have open clockwise geometries.
