Objectives: This study aims to establish a detailed chronology of Quaternary glaciations in the Yajiageng area of Gongga Mountain, eastern Tibetan Plateau. It seeks to clarify the timing and extent of past ice advances. Methods: We applied some methods in this study including field geomorphological survey, cosmogenic nuclide dating, laboratory analysis and ESR for age calculation. Results: In this paper, on the basis of field glacier geomorphological survey and 10Be exposure age analysis of moraine gravel. Five stages of Quaternary glaciation in Yajiazhi area, namely, the Little Ice Age, the New Ice Age, the Last Ice Age, the MIS 5 Ice Advance, and the MIS 6 Ice Advance, are identified. Conclusions: Yajiageng preserves evidence of five Quaternary glaciations, resolving debates on the timing of pre-LGM advances.
