Low‐Temperature Thermochronologic Response to Magmatic Reheating: Insights From the Takab Metallogenic District of NW Iran, (Arabia‐Eurasia Collision Zone)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 24, Issue 1, January 2023., 2023
Abstract The interpretation of low‐temperature thermochronology (LTT) data in magmatic and metallogenic provinces requires a knowledge of the geothermal field through time. There, the challenge is differentiating rapid cooling following transient perturbations of the geotherms (reheating) from exhumational cooling induced by erosion during tectonic ...

Mississippian-Asselian (early carboniferous-early permian) foraminiferal faunas and biostratigraphy of the Shahreza-Abadeh regions (The Sanandaj-Sirjan Zone), Iran / Shirin Fassihi [PDF]

open access: yes, 2017
The Mississippian‒Asselian (Early Carboniferous‒Early Permian) foraminiferal faunas and biostratigraphy were studied in three sections of the Shahreza‒Abadeh regions, in the Sanandaj-Sirjan Zone, in Iran. These sections with a thickness of about 528‒1180

Geodynamic evolution of the Sanandaj-Sirjan Zone, Zagros Orogen, Iran

open access: yesTURKISH JOURNAL OF EARTH SCIENCES, 2015
Abstract: The Sanandaj-Sirjan Zone is a metamorphic-magmatic belt, associated with the Zagros Orogen and part of the Alpine-Himalayan orogenic system in Iran. Stratigraphic, metamorphic, magmatic, and tectonic evidence presented here indicates that the Sanandaj-Sirjan Zone, the Central Iranian Microcontinent, and the North West Iranian Plate were a ...

Tourmaline geochemistry in the granitoids of the Sanandaj–Sirjan Zone (A case study of Astaneh and Aligudarz granitoids) [PDF]

open access: yesپترولوژی
IntroductionTourmaline exhibits a broad range of chemical variability (Hawthorne and Henry, 1999). This diverse and complex chemistry reflects a clear genetic link between tourmaline and the environment from which it crystallized.

Investigation of the formation processes in the mafic enclaves of Naqadeh plutonic rocks assemblage by zircon U-Pb dating, Sr-Nd isotopic ratios, and amphibole composition [PDF]

open access: yesپترولوژی, 2021
Naqadeh intrusive pluton is composed of two distinct sections of felsic (40 Ma age) and mafic (99 Ma age) rocks. The granitoid rocks of Naqadeh pluton have different types of mafic enclaves, including mafic microgranular enclaves (MME) and quartz ...
