The eclogites of the Marun–Keu complex, Polar Urals (Russia): f luid control on reaction kinetics and metasomatism during high P metamorphism
The Marun–Keu complex (Polar Urals, Russia) is a poorly known member of a group of high P complexes outcropping along the length of the Uralide orogen. The central and southern parts of the complex are metamorphosed at high P, medium T conditions (Tmaxf600–650 jC and Pf14–17 kbar) and differ from its northern part and the rest of the Uralian high P complexes which are metamorphosed at blueschis...
متن کاملEclogite-facies vein systems in the Marun-Keu complex (Polar Urals, Russia): textural, chemical and thermal constraints for patterns of fluid flow in the lower crust
Metasomatic amphibole-eclogite sequences grew in selvages of quartz veins from the Marun-Keu complex (Polar Urals, Russia) during high-pressure metamorphism. Relicts of a pre-metasomatic eclogitefacies assemblage are present in the wallrock layers as irregular patches. Wallrock interstitial quartz trails lying at a high angle to reaction fronts provide evidence for grain-scale pore channelisati...
