Mineralogical and Geochemical Constraints of Jurassic Fossil Hydrothermal Alteration Associated with an Calc-Alkaline Volcano-Sedimentary Complex in Sanandaj-Sirjan Zone, Southwest of Iran

Metamorphic evolution of high-pressure Quartz Schists in the Chadegan metamorphic complex, Sanandaj-Sirjan zone, Iran

The Chadegan metamorphic complex is a WNW-ESE- trending antiformal structure located in Sanandaj-Sirjan structural zone, Iran.The inner core of the structure is made of orthogneiss, containing eclogitic lenses. Schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. Two main deformational episodes have been documented in theschists an...

SOGHAN COMPLEX AS AN EVIDENCE FOR PALEOSPREADING CENTER AND MANTLE DIAPIRISM IN SANANDAJ-SIRJAN ZONE (SOUTH-EAST IRAN)

New Constraints on Deformation History of the Zagros Hinterland: Evidences from Calcite Twin Morphology and Geothermometery in Sargaz Complex, Sanandaj-Sirjan Zone, SE Iran

In order to investigate deformation history preserved in the calcite twins in the hinterland of Zagros, several samples have been collected from calcschists of the Paleozoic Sargaz complex in the Faryab area, SE Iran. These samples are related to F1-recumbent folding and thrust shear zones. The twin width is about 1 and 3.8 µm (thin-twin regime); the twin strain amounts 5 and 10%; twin intensit...

alkaline basic dykes in the central part of sanandaj-sirjan zone (iran)

there are three different basic dykes in the northeast of golpayegan area, central part of sanandaj-sirjan zone (ssz) including: mylonitic gabbros (group 1), alkali dioritic-basanitic dykes (group 2) and alkali monzogabbroic to monzodioritic dykes (group 3). group 2 and 3 cut post-collisional rocks and are related to after subduction processes of neo-tethys. geochemistry characteristic of studi...
