Mineral chemistry and thermobarometry of amphibolites from the Qotur metamorphic complex (West Azerbaijan Providence, NW Iran)
The Qotur metamorphic complex consists of metabasites, gneisses, marbles and calc-silicates as well as serpentinites which is cropped out at the west border of West Azerbaijan and Turkey. The amphibolites from the Qotur metamorphic complex can be classified as two types of ortho- and para-amphibolites. Minerals in this ortho-amphibolite are hornblende, plagioclase, zircon, titanite, and opaque ...
متن کاملPetrography, mineral chemistry and thermobarometry of amphibolites from the Allahyarlu metamorphic complex -Ardebil, NW Iran
The pre-Eocene Allahyarlu ophiolitic- metamorphic complex is exposd in the core of the Allahyarlu anticline in the northwest of Iran and northeast of Meshginshahr. This complex consists of a variety of schist, gneiss, amphibolite and metadibase rocks with serpentinite and tectonic slices including gabbro, dunit, marble and diabase. Amphibolites can be divided into garnet-free amphibolite and ga...
متن کاملMineralogy and geothermo-barometry of metapelitic schists, amphibolites and garnet amphibolites from Gol-Gohar metamorphic complex, SW Sirjan, Central Iran.
The Gol-Gohar metamorphic complex, a part of east Sanandaj-Sirjan zone, is located 55 km southwest of Sirjan. This complex consists of metapelitic, metapsammitic and metacarbonatic rocks. Field and geochemical evidence indicate that these sedimentary protolith sequences were composed of shale and sandstone alternation with carbonate layers in the upper parts. In the studied metapelites, garnets...

متن کاملHigh-Pressure Marbles from the Nahavand Area in the Sanandaj-Sirjan Metamorphic Belt, Iran
Marbles containing high-pressure mineral assemblage was found from the Sanandaj-Sirjan metamorphic belt in the Nahavand area in western Iran. The high-pressure marbles occur as small bodies or lenses within pelitic schist layers and show compositional banding of carbonate- and silicate- rich bands. Textural analysis revealed two metamorphic stages. The early stage is testified by relicts of ...
