High-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 کاملMetamorphic 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...

متن کاملmetamorphic evolution of high-pressure quartz schists in the zhan metamorphic complex, sanandaj-sirjan zone, iran
the study area is located at the sanandaj-sirjan zone in the west and north-west of azna and north-east of doroud, iran. the quartz-schists are divided into two main groups: amphibole-quartz schist and garnet-quartz schist. field and microstructural studies show several deformational phases. the d1 episode which is represented by s1, matches with m1 metamprphism and d2 deformation matches with ...
