This study examines the late Quaternary glacial history of Suru Basin and its associated tributary valleys (i.e., Achambur, Kangriz, Shafat, Rangdum, and Pensilugnpa), western Himalaya, based on the data collected from field surveys (2015–2019), satellite images, and optically stimulated luminescence (OSL) dating. The glaciers in Suru Basin have fluctuated greatly throughout the Marine Isotope Stages (MIS) 3 and 2 to the Little Ice Age (LIA), and are critical in understanding the linkages between regional and global climate change. Here, we present a detailed record of five major glacial advances of decreasing magnitude, dated 33–23 ka, 16 ka, 13–11 ka, 10–7.3 ka, 2.8–2.3 ka, and a minor advance dated 0.7–0.4 ka. These five major glacial advances are named from oldest to youngest as Suru-I to V, based on their optical chronology, geographical position, moraine stratigraphy, and glacially polished rock surfaces. Whereas, the equilibrium-line altitude (ELA) ascended by ∼538 m from the oldest glacial advance (Suru-I) to the present-day, followed by four other events (Suru-II, III, IV, and V) with ascended ELAs of ∼522, ∼399, ∼243, and 215 m, respectively. Suru Basin has lost ∼502 km² in its glaciated area and ∼163 km³ in ice volume from Suru-I to the present-day. The magnitude of glacier extent decreased from the MIS 3 and 2, early to late-Holocene, and LIA. The timing of these glacial advances is coarsely in agreement with North Atlantic millennial-scale climate oscillations (Heinrich events), signifying the probable correlation between these abrupt climate changes and glacial fluctuations in this semi-arid region of the Himalaya.

本研究根据实地调查（2015-2019 年）和卫星图像收集的数据，研究了喜马拉雅西部苏鲁盆地及其相关支流河谷（即阿尚布尔、康格里兹、沙法特、朗杜姆和彭西卢格帕）的晚第四纪冰川历史, 和光受激发光 (OSL) 测年。苏鲁盆地的冰川在整个海洋同位素阶段 (MIS) 3 和 2 到小冰河时代 (LIA) 期间波动很大，对于了解区域和全球气候变化之间的联系至关重要。在这里，我们详细记录了 33-23 ka、16 ka、13-11 ka、10-7.3 ka、2.8-2.3 ka 和 0.7-0.4 ka 的次要冰川进展的五个规模递减的主要冰川进展。这五个主要的冰川进展根据它们的光学年表从最老到最年轻命名为 Suru-I 到 V，地理位置、冰碛地层和冰川抛光的岩石表面。然而，平衡线高度 (ELA) 从最古老的冰川推进 (Suru-I) 到今天上升了约 538 m，随后是其他四个事件 (Suru-II、III、IV 和 V)。 ELA 分别为~522、~399、~243 和 215 m。苏鲁盆地损失约 502 公里²在其冰川区，从 Suru -I 到现在的冰量约为 163 km ³。冰川范围的大小从 MIS 3 和 2、早到晚全新世和 LIA 减少。这些冰川推进的时间与北大西洋千年尺度的气候振荡（海因里希事件）大致一致，表明这些突然的气候变化与喜马拉雅半干旱地区的冰川波动之间可能存在相关性。
