Fig. 2

Comparison of the component Gaussians of 10Be moraine ages from the TPSM and its seven subregions (10Be moraine ages from Supplement, Table S1). The black curve represents the summed Probability Density Estimate (PDE), while the differently colored shadings indicate the component Gaussians separated from the PDE. From top to bottom (a-h) are that for the TPSM, Pamir, Tianshan, SE Tibet, NE Tibet, Central Tibet, E Himalaya, and W Himalaya, respectively. The font colors corresponding to the Gaussians indicate their peak ages and 1-sigma internal uncertainties. The black box contains the bandwidth estimation pattern (MAAD) and their corresponding values, as well as the model fit quality (R2). The numbers in parentheses represent the probability of each component Gaussian. The five gray rectangles represent the five peak retreat stages we defined.
