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 ...

The controls on the thermal evolution of continental mountain ranges

open access: yesJournal of Metamorphic Geology, Volume 40, Issue 7, Page 1235-1270, September 2022., 2022
Abstract This paper examines the controls on the thermal evolution of continental mountain ranges and investigates how pressure (P) and temperature (T) estimates from metamorphic rocks can be used to reconstruct the thermal histories of orogenic belts.

Mineral chemistry and geothermobarometry of metabasites of the Majerad igneous-metamorphic complex (SE of Shahrood)

open access: yesJournal of Economic Geology, 2020
Introduction Thermobarometric models based on the chemical equilibrium among coexisting mineral-mineral or mineral-melts pairs are useful tools widely used to estimate the P-T path and chemical evolution during igneous processes. The high sensitivity of
