Very high-pressure orogenic garnet peridotites.
Mantle-derived garnet peridotites are a minor component in many very high-pressure metamorphic terranes that formed during continental subduction and collision. Some of these mantle rocks contain trace amounts of zircon and micrometer-sized inclusions. The constituent minerals exhibit pre- and postsubduction microstructures, including polymorphic transformation and mineral exsolution. Experimen...
متن کاملGeothermobarometry and petrogenesis of Chahar Dahane peridotites, West margin of Makran zone, Hormozgan province, Iran
The study area known as ‘Chahar-Dahaneh’ is part of the Iranian southeast ophiolites related to Alpian-Himalayan Mesozoic orogeny belt, and is located in the western margin of the Makran subduction zone. Chahar Dahaneh peridotite section consists of three major lithologies including: 1.dunite lenses 2. harzburgites and 3. Lherzolite. Based on electron microprobe analysis ,we estimated pressure ...
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 کاملMineralogy, metamorphism and geothermobarometry of the Ghandab metamorphic Complex, SE Fariman, NE Iran
The study area is located about 110 kilometers southeast of Mashhad and approximately 40 kilometers southeast of Fariman. The area is considered to be a part of the central Iran zone. It includes metamorphic rocks with different protoliths consisting of pelitic, carbonate and quartz - feldspathic rocks. The metamorphism in the study area is considered to be a contact regional metamorphism with ...
