摘要
巴颜喀拉山脉南端位于四川省阿坝县、壤塘县与马尔康县交界地区。该区古冰川遗迹广泛分布 ,安纳尔措地区末次冰期晚阶段冰碛垅保存有 7条 ,系统的石英ESR测年资料表明 ,它们均属新仙女木期 ,构成完整的冰退序列。
The southern end of the Mts.Bayan Har lies in common boundary area of Aba,Zamtang and Barkam counties.There are widespread fossil glacier traces here,including 7 lateral moraine bars at the terminal glacial stage in the Annaer Co area.Systematic ESR dating indicates they have the whole glacier regression sequence of the Younger Dryas.
