Petrography and application of mineral chemistry and thermobarometry of amphibolites in Jandaq metamorphic complex: Evidence of paleo-tectonic events in Central Iran

Arefeh Heidarianmanesh; Seyed Mohsen Tabatabaimanesh; Narges Shirdashtzadeh

Volume 32, Issue 4 , December 2022, , Pages 119-142

https://doi.org/10.22071/gsj.2022.329201.1981

Abstract
  Based on field observation and petrographic evidence, by progress in metamorphic degrees, a wide variety of metabasites have formed following the metamorphism at amphibolite facies (metamorphism M1) in the east of Jandaq. Thermobarometry of plagioclase- amphibole pairs indicate temperature ranges were ...  Read More

Mineral chemistry and petrogenesis of metabasites of metamorphic - igneous Shotor-Kuh complex (SE Shahrood) an indicator for evolution of intracontinental extensional basins of late Neoproterozoic

S. Shekari; M. Sadeghian; M. Zhai; H. Ghasemi; Y. Zou

Volume 27, Issue 105 , December 2017, , Pages 167-182

https://doi.org/10.22071/gsj.2017.54181

Abstract
  Metamorphic - igneous Shotor-Kuh complex is located in the 80 km of SE Shahrood and in the northern edge of the central Iran structural zone. This complex includes a wide lithological composition range such as metapelite (micaschists and gneisses), metapsammites, metabasites (amphibolite and garnet amphibolite), ...  Read More

Mineral chemistry and P-T estimations of Grt-Cpx amphibolites, SE Qarehaghaj-East Azerbaijan province

M. Advay; R. Hajialioghli; M. Moazzen

Volume 26, Issue 104 , September 2017, , Pages 29-42

https://doi.org/10.22071/gsj.2016.50165

Abstract
  The study area is located in the Central Iran Zone, in the view of tectonic subdivisions of Iranian terrains. The main outcropping rock types are metabasites and amphibolites having Precambrian age. The amphibolites have been classified as Ep-amphibolite, normal amphibolite, Grt-amphibolite and Grt-Cpx ...  Read More

Petrography and mineral chemistry of amphibolitic fragments in the south of Nain Ophiolite skarns, Central Iran

N Shirdashtzadeh; G Torabi; R Samadi

Volume 26, Issue 102 , March 2017, , Pages 153-164

https://doi.org/10.22071/gsj.2017.44135

Abstract
  Some dark green fragments of amphibolites are found within skarns at the south of Nain Ophiolite at the northeast of Nain city. They are similar to ortho-amphibolites (metamorphosed basic rocks) of this ophiolite in hand specimen, but mineralogically they are composed of amphibole (magnesio-hornblende, ...  Read More

Petrology and geochemistry of amphibolites from Southeast of Siyah-Cheshmeh, NW Iran

R Hajialioghli; H Fakharinezhad; M Moazzen

Volume 25, Issue 99 , June 2016, , Pages 111-122

https://doi.org/10.22071/gsj.2016.40795

Abstract
  The study area (Siyah-Cheshmeh), is located to the south Maku in the Khoy-Maku ophiolite zone. The various outcropped metamorphic rocks include serpentinites, metabasites (green schist, amphibolite) and meta-pelitic rocks (slate, mica-schist) with interlayers of marble and quartzite. The amphibolites ...  Read More

Petrography of Gelmandeh Metamorphic Complex with Reference to Microscopic Deformation

A Gourabjeri; M.H Emami

Volume 23, Issue 90 , March 2014, , Pages 151-164

https://doi.org/10.22071/gsj.2014.43979

Abstract
  Gelmandeh Massive is located north-east of Saghand, in Yazd province. From tectonics point of view it belongs to Central Iran, the Kalmard_Posht-e-Badam Block. The metamorphic complex comprises amphibolites, marble, schist, quartz- feldspatic gneisses. The amphibolites are of three types. Namly: Hornblendite ...  Read More

Changing Rare Earth and Trace Elements during the Migmatization of the Qori Metabasic Rocks, Neyriz, SW Iran

A. N. Fazlnia

Volume 22, Issue 86 , December 2012, , Pages 161-170

https://doi.org/10.22071/gsj.2012.54082

Abstract
  A barrovian-type metamorphism occurred in the mafic rocks from the Qori complex (South Sanandaj - Sirjan zone), because of a regional arc-related metamorphism with a peak metamorphic condition of 700 °C and 8.5 kbar at 147 million years ago. As a result of the process, the rocks changed to migmatite. ...  Read More
