Be-10 dating of alluvial deposits from Southeastern Iran (the Hormoz Strait area)

摘要

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 Be-10 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 Be-10 kyr.
