阶地形成的时间相对于冰期-间冰期循环，以及什么因素控制了这个时间，如气候变化和/或隆起，是有争议的。在这里，我们提出了一个研究的阶地沿着雅哲库河使用电子自旋共振（ESR）测年和分析的沉积特征，以建立阶地形成的时间和评估的强迫机制，已提出。雅哲库河发源于青藏高原东部的海子山，流经冰川槽。该山脉在第四纪期间被抬升，并多次被冰帽冰川化。四个最高的主要阶地（T5，T4，T3和T2）是气候和构造影响的结果。斯特拉特阶地T5-T2分别形成于MIS 16、MIS 12、MIS 6和MIS 3-MIS 4期海子山冰川扩张期。四个阶地的主要加积阶段发生在MIS 16，12，6和2的末端的冰消期。向下切割，这导致了四个阶地的产生，紧随着T5-T2砾石单元的沉积。这些切口发生在MIS 16-15、MIS 12-11、MIS 6-5和MIS 2-1之间的过渡期间。
The timing of terrace formation relative to the glacial–interglacial cycle and what factors control that timing, such as changes in climate and/or uplift, are controversial. Here we present a study of the terraces along the Yazheku River using electron spin resonance (ESR) dating and analysis of the sedimentary characteristics in order to establish the timing of terrace formation and to assess the forcing mechanisms that have been proposed. The Yazheku River flows in glacial trough leading from the Haizi Shan, on the eastern Tibetan Plateau. The range was uplifted during the Quaternary and repeatedly glaciated by ice caps. The four highest major terraces (T5, T4, T3, and T2) are the result of both climatic and tectonic influences. Strath terraces T5–T2 were created during Haizi Shan glacial expansions during MIS 16, 12, 6 and 3–4, respectively. The major aggradation phases of the four terraces occurred during the deglaciations at the ends of MIS 16, 12, 6, and 2. Down-cutting, which led to the generation of the four terraces, immediately followed the deposition of the T5–T2 gravel units. These incisions occurred during the transitions between MIS 16–15, MIS 12–11, MIS 6–5, and MIS 2–1.
