Detrital zircon U-Pb-He double dating: A method of quantifying long-and short-term exhumation rates in collisional orogens

Wang, Christina Yan; Campbell, Ian; Reiners, Peter; Allen, Charlotte M

Description

A U-Pb-He double-dating method is applied to detrital zircons with core-rim structure from the Ganges River in order to determine average short- and long-term exhumation rates for the Himalayas. Long-term rates are calculated from the U/Pb ages of metamorphic rims of the grains that formed during the Himalayan orogeny and their crystallization temperatures, which are calculated from the Ti-in-zircon thermometer. Short-term rates are calculated from (U-Th)/He ages of the grains with appropriate...[Show more]
