Guxiang 和 Baiyu 冻结成冰是西藏的高原的二以前公认的本地冻结成冰。他们广泛地作为参考标准被使用了在西藏的高原和它的包围的山上分类 LateQuaternary 冻结成冰。然而，两冻结成冰的数字年表一直在缺乏。在这研究， cosmogenic ~(10 ) 正在标明日期被承担定义预定这二冻结成冰。Guxiang 和 Baiyu 冻结成冰的冰河扔的表面大石头有 112.9 ± 1 6.7-136.5 ± 1 的暴露年龄 5.8 ka BPand 11.1 ± 1 .9-18.5+2.2 ka BP 分别地。到海洋的同位素的 Guxiang 和 Baiyu Glaciationscorrespond 分别地上演 6 和 2，是可能的。

英文摘要：

Guxiang and Baiyu Glaciations are two previously recognized local glaciations of the Tibetan Plateau. They have been widely used as the reference standard for classifying Late Quaternary glaciations on the Tibetan Plateau and its surrounding mountains. However, the numerical chronologies of both glaciations have been lacking. In this study, cosmogenic They dating was undertaken to define the timing of these two glaciations. The surface boulders deposited by the glaciers of the Guxiang and Baiyu Glaciations have exposure ages of 112.9±16.7-136.5±15.8 ka BP and 11.1±1.9-18.5±2.2 ka BP, respectively. It is likely that the Guxiang and Baiyu Glaciations correspond to marine isotope stages 6 and 2, respectively.
