Late Campanian (74–71 Ma) Arabia–Eastern Anatolia Collision and Its Geodynamic Implications

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The East Anatolian Plateau is a major collisional feature within the Tethyan realm formed as a late‐stage result of the collision between East Anatolia and the Arabian Platform. The timing of this collision is highly debated, with estimates from the Late Cretaceous to the Miocene.

Middle Cretaceous Andean‐Type Arc Evolution in the Sanandaj–Sirjan Zone (Shalair Valley), Iraq: New Geochronological and Geochemical Constraints

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±

path of the Boroujerd Complex, north‐west Sanandaj–Sirjan Zone, western Iran: Insights from phase equilibrium modelling and thermobarometry

, 2021
Variations in the pressures and temperatures of metamorphism reflect the complexity of collisional orogenic systems. In the north-west Sanandaj–Sirjan Zone of western Iran, migmatites in the Boroujerd area record earlier dynamothermal metamorphism ...

Deciphering Asynchronous Teleconnections: How Dynamic Time Warping Reveals the Hidden Drivers of Iranian Drought

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Identifying robust precursors for seasonal drought is a central challenge in Earth system science, traditionally approached with linear methods that often fail to capture the complex, asynchronous nature of teleconnections. These methods, by assuming fixed‐phase relationships, can overlook or misrepresent crucial climate drivers.
