Prograde amphibolite facies to ultrahigh-pressure transition along Nordfjord, western Norway: Implications for exhumation tectonics
[1] The Nordfjord area of western Norway hosts one of the best known provinces of ultrahigh-pressure (UHP) rocks in the world, yet the nature of the transition from the UHP rocks into surrounding amphibolite-facies crust has remained unclear. New thermobarometry of phengiteand kyanite-bearing eclogites shows that this transition is unbroken by major structures: the pressure and temperature grad...
متن کاملAn albite-anorthite assemblage in low-grade amphibolite facies rocks
Poikiloblastic amphibole schists from an ophiolite series in the vicinity of the Tertiary Bergell granite contain the assemblage albite (An 0)-anorthite (An 95), actinolite-pargasite, together with clinozoisite. TEM illustrates how large andesine crystals with a periodic APB (anti-phase boundaries) structure of e plagioclase change over a few hundred angstroms to pure albite and pure PT anorthi...
متن کاملOre mineralogy and fluid inclusions constraints on genesis of the Muteh gold deposit (western Iran)
The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...
متن کاملA new species of Anarta Ochsenheimer, 1816 from Mongolian and Russian Altai (Lepidoptera, Noctuidae).
Anarta Ochsenheimer, 1816 is a hadenine genus restricted to Palaearctic and Nearctic Regions. The genus includes about 80 described species and subdivided into seven subgenera (Hacker 1998; Fibiger et al. 2011): Trichoclea Grote, 1883 (= Hadula Staudinger, 1889), Cardiestra Boursin, 1963, Ptochicestra Hacker, 1998, Aglossestra Hampson, 1905, Calocestra Beck, 1991, Pulchrohadula Hacker, 1998 and...
متن کاملEclogite-facies fluid infiltration: constraints from dO zoning in garnet
In situ analysis reveals that eclogite-facies garnets are zoned in dO with lower values in the core and rims that are *1.5 to 2.5 % higher. This pattern is present in 9 out of 12 garnets analyzed by SIMS from four orogenic eclogite terranes, and correlates with an increase in the mole fraction of pyrope and Mg/Fe ratio from core to rim, indicating prograde garnet growth. At the maximum temperat...
