Reply to comment by Zhao et al. on “Hydrothermal events in the Linzizong Group: Implications for Paleogene exhumation and paleoaltimetry of the southern Tibetan Plateau”

In their comment on our publication about the discovery of two hydrothermal events in the Linzizong Group (Huang et al., 2022), Zhao et al. question the reliability of our thermochronologic data and the existence of hydrothermal events experienced by these rocks. They argue that their field and microscopic observations, as well as paleomagnetic studies, indicate that the lower Linzizong volcanic rocks preserve primary igneous textures and paleomagnetic signals. In this reply, we address these issues raised by Zhao et al., provide more field evidence, and conduct additional analyses that show that their assertions are not supported. We emphasize that hydrothermal events related to magmatism and deformation have systematically induced resetting of thermochronologic, stable isotopic, and paleomagnetic records of the lower Linzizong Group in the Linzhou basin of southern Tibet.
