图6 玉东曲末次冰消期冰川变化与气候记录对比

Fig. 6 Climatic records relative to 10Be-based moraine chronologies in the Yudongqu Valley. The yellow band corresponds with Heinrich Stadial 1 （HS1）. The light grey band indicates part of the global LGM： probability density function （PDF） plot of the glacial culminations in the Yudongqu Valley. Thin red lines show PDF for individual samples with potential outliers excluded. Thick black lines represent the cumulative probability distribution of the boulder age population （a）； ice-volume equivalent sea level［78］ （b）； Northern Hemisphere summer solar insolation intensity at high and local latitudes［77］ （c）； the stalagmite δ18O record from Xiaobailong Cave， southern HDM［83］ （d）； chironomid-inferred mean July temperature record from Lake Tiancai［84］ （e）； SSTs reconstructed from Andaman Sea core RC12-344［86］ （f）； synthesized atmospheric CO2 concentrations in Antarctic ice cores［88-91］ （g）
