Fission track thermochronology of the Tuwu-Yandong porphyry Cu deposits, NW China: Constraints on preservation and exhumation

The Carboniferous Tuwu-Yandong porphyry Cu deposits, located in the eastern Tianshan, are the largest porphyry Cu deposits in the Xinjiang province, China. This work presents new zircon and apatite fission track (ZFT and AFT) data from this porphyry Cu deposit, combined with inverse thermal modeling and previously published ages to reveal their preservation condition and exhumation history. Specifically, four cooling episodes are recognized:...
