A key area for the understanding of the southeastern Iran geodynamics, the Hormoz Strait area, was investigated. Tectonically active, it provides useful sequences of Quaternary deposits whose deposition may have ended either when the climate dried or when the tectonic activity uplifted the riverbed. In-situ produced cosmogenic 10 Be provides surface abandonment ages at 5.6±0.6, 8.4±1.0, 12.8±1.0, 20.1±1.5, and 44.0±3.4 10 Be kyr.Located at the transition between the Mediterranean Winter Rain and the Indian Monsoon domains, and south of the northernmost position of the ITCZ (InterTropical Convergence Zone), the studied area is very sensitive to climate changes. Some of the calculated 10 Be abandonment ages are within the entire investigated area coincidental with large-scale climate shifts: the offset of the mid-Holocene humid period (5.6±0.6 10 Be kyr), the onset of the dry Younger Dryas cold and dry episode (12.8±1.0 10 Be kyr), and the end of the Last Glacial Maximum (LGM; 21±2 kyr) at 20.1±1.5 10 Be kyr. These events correspond to large-scale changes in atmospheric circulation linked to global climate changes, and/or to sea-level fluctuations in the Persian Gulf, which was totally dry during the LGM.Locally observed abandonment ages at 8.4±1.0 and 44.0±3.4 10 Be kyr may likely be related to enhanced tectonic activity without regional impact.
