The zircon story of the Pearl River (China) from Cretaceous to present

Provenance of Neogene sandstones in western Taiwan traced with garnet geochemistry and zircon geochronology

“…The natural sediment flux has been strongly modified by human activities, including extensive sand mining and construction of dams across the mainstem and all major tributaries (Wu et al, 2016;Zhang et al, 2012). A reconstruction of paleodrainage evolution from Cretaceous to present is provided in He et al (2019).…”

“…In this study, we address this major paleogeographic problem by multitechnique provenance analysis. Petrographic and heavy-mineral data sets collected with the same methods and following the same criteria on Neogene Taiwan sandstones (Nagel et al, 2014), modern sand of western Taiwan rivers Resentini et al, 2017), modern sediment carried by the Pearl River and smaller rivers of coastal SE China (Garzanti et al, 2020;He et al, 2019He et al, , 2020, and modern Yangtze River sand (Vezzoli et al, 2016) are integrated here with Raman spectroscopy analysis of detrital garnet (Figure 1). Also used in this study are published zircongeochronology data from river sand in mainland China and Taiwan from Deng, Yang, Li, et al (2017), He et al (2013), Liu et al (2017), Xu et al (2007), Xu et al (2014Xu et al ( , 2016, Zhao et al (2015), and Zhong et al (2017).…”
