托木尔河源于天山最大现代冰川作用中心托木尔峰西南坡的托木尔冰川,在第四纪冰期与间冰期的气候旋回中,遗留下了5套形态较为完整的冰川沉积.应用ESR测年技术对第一与第二级冰碛阶地(对应于第三套冰碛中地形较完整部分的冰碛,分布在托木尔河大桥与古库瓦河汇合口之间)以及第五套最高冰碛平台进行测年,依据初步的测试结果并结合地貌地层学原理可得出:5套冰碛分别形成于小冰期、新冰期、末次冰期、MIS6和MIS12,每次冰川作用过程中还包含着若干次级的冰川波动.根据现存的冰碛地形可推得:新冰期、末次冰期与MIS6时的冰川为山谷冰川,规模最盛时冰川长分别为47 km、60 km、≥70 km.
The Tuomo River originated from the Tuomoer glacier, which originated from the southwestern slope of Mount Tomoh, which is the center of the largest modern glaciation in the Tianshan Mountains, leaving 5 sets of glacier deposits with relatively complete morphology during the Quaternary and interglacial climatic cycles. The dating technique has a significant impact on the first and second moraine terraces (corresponding to the more complete part of the moraine in the third moraine, distributed between the confluence of the Tocumho Bridge and the Khuku River) Based on the preliminary test results and the principles of geomorphology, it can be concluded that five sets of moraines were formed in the small ice age, the new ice age, the last ice age, MIS6 and MIS12 respectively. During each glacial process There are also several secondary glacier fluctuations, which can be deduced from the existing moraine topography: in the new glacial period, glaciers in the last glacial period and MIS6 were valley glaciers, and the glaciers at the peak were 47 km, 60 km and 70 km respectively .
