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

“…Heat transfer will occur through thermal conduction and convection of fluids circulating in porous and fractured host rocks (e.g., Norton & Taylor, 1979; Parmentier & Schedl, 1981; Turcotte & Schubert, 2002). The occurrence of convection is more evident in metallogenic districts where fluids rising along faults and fracture zones or highly permeable rocks lead to localized mineralization processes (e.g., Fu et al., 2010; Luijendijk, 2019; Sánchez et al., 2021). To explore and quantify the transient thermal effect of magmatic intrusions on host rocks (i.e., the spatial distribution, magnitude, and timing of the perturbation with and without fluids), we designed a forward, 3D numerical thermal model using the TOUGH2 code (Transport Of Unsaturated Groundwater and Heat; W. M. Kissling, 1995; Pruess, 1991, https://tough.lbl.gov/).…”

“…However, the interpretation of LTT data sets in regions characterized by widespread and prolonged magmatic activity, can be complicated by transient episodes of heating and cooling (i.e., reheating) that could be misinterpreted as episodes of burial and exhumation, respectively (e.g., Murray et al., 2018). Transient thermal events can be further amplified by the effect of fluids rising along faults and fracture zones or through highly permeable rocks, which can affect the heating/cooling rate of the rocks and lead to localized mineralization processes (e.g., Fu et al., 2010; Luijendijk, 2019; Sánchez et al., 2021). These complexities highlight the need to tackle the exhumation history of magmatic provinces through a multidisciplinary strategy integrating different data sets.…”
