Deformation flow analysis and symmetry of Goushti shear zone, Sanandaj-Sirjan metamorphic belt, Iran
Finite strain and vorticity analyses were carried out in the deformed conglomerate and micro-conglomerate of Goushti shear zone in the Sanandaj-Sirjan metamorphic belt (Zagros Mountains Iran). These deformed rocks are bounded between two NE and SW major thrust faults. Finite strain measurements on three principal planes of strain ellipsoid show the higher amounts of strain ratios near the major...
متن کاملMineral 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 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 ...
متن کاملBiotite and Hornblende Composition Used to Investigate the Nature and Thermobarometry of Pichagchi Pluton, Northwest Sanandaj-Sirjan Metamorphic Belt, Iran
Pichagchi pluton is situated in the northeastern part of the Soursat complex in Sanandaj-Sirjan metamorphic belt of Iran. The pluton with the age of 74.20 Ma is composed mainly granodiorite, diorite, and tonalite in which mafic minerals are biotite and amphibole. In this study, composition of minerals used to describe the nature of the granitic magma and estimate the pressure and temperature at...
