| 英文摘要 | Layered cave passages formed on the walls of the Qianyou River valley in the middle part of the Qinling Mountains since the Pleistocene due to the intermittent uplifts. 12 speleothem samples near ruins of galaeowater tables in 3 cave passages are dated by using the Th-230 method. The results show that the 3 eaves began to uplift (358 38) ka, (247+/-28) ka, (118+/-19) ka ago respectively. Given the differences of elevation between the eaves, we could obtain the downcutting rates of the valley: (0.23+/-0.02) mm/a during 358 - 247 ka, (0.19+/-0.03) mm/a during 247-118 ka, and (0.51(0.08) mm/a since 118 ka. This implies that more and more strong uplifting sustained in the middle part of Qinling since 358 k. |
