Volume 32, Issue 2 , July 2022, , Pages 133-148

https://doi.org/10.22071/gsj.2021.295726.1920

Abstract
  Takhte-Soleyman ortho-amphibolites as a part of Takab metamorphic complex are located in Northeast Takab. These rocks consist of amphibolite, Garnet-amphibolite, Kyanite-Garnet-amphibolite, Hornblendite and Epidote-amphibolite. Petrography and whole- rock geochemistry show that basalt, andesite and/or ...  Read More

Volume 28, Issue 112 , August 2019, , Pages 289-302

https://doi.org/10.22071/gsj.2018.99811.1276

Abstract
  Granitoid bodies of west of Zanjan with Precambrian age are located in northwest of central Iranian structural zone. Based on field observations and microscopic studies, these bodies contain tonalite, granodiorite and monzogranite. Tonalite are I-type, calc-alkaline, and peraluminous (206Pb/238U age ...  Read More

Common Melting Reactions and Their Characteristics in the Alvand Aureole Metapelites, Hamadan

A. Saki; A. A. Baharifar

Volume 21, Issue 82 , December 2011, , Pages 165-172

https://doi.org/10.22071/gsj.2011.54452

Abstract
  Intrusion of the Alvand complex (intrusions formed during Jurassic) into the host metapelitic rocks (schists) created pelitic hornfelses and anatectic migmatites in the Alvand aureole. Partial melting in the Alvand aureole was restricted to pelitic bulk compositions. Existing of spinel-quartz minerals ...  Read More

Fluid Pressure and the Lack of Chloritoid in Metapelites: Implications from Hamedan Area, Sanandaj- Sirjan Zone, Iran

A. A. Baharifar

Volume 19, Issue 76 , January 2010, , Pages 135-140

https://doi.org/10.22071/gsj.2010.55671

Abstract
  Chloritoid as one of the common metamorphic mineral in low to medium grade metapelites, is absent in metapelitic rocks of Hamedan area. Comparing with geochemical limitations for Chloritoid appearance in metapelites, whole rock composition of the area is suitable for Chloritoid formation. Since P, T ...  Read More
