Terrestrial loess palaeosol sequences (LPS) are the most extensive paleoclimate archives documenting dynamic sedimentary processes in response to glacial (cold-dry) and interglacial (warm-wet) phases. In the present study, we provide chrono-stratigraphy and paleoenvironmental implications of a 600 cm LPS outcrop from the Kashmir Valley, Western Himalaya. The Optically Stimulated Luminescence (OSL) dating revealed development of polycyclic palaeosol units with variable thickness, a parent loess horizon and pedogenically modified loess during the last ~65.8 ± 7.2 ka to ~14.7 ± 5.4 ka. The multiproxy analysis revealed four major climate phases that prevailed between 65.8 ± 7.2 ka to 14.7 ± 5.4 ka. Sediment deposition from ~800 to ~640 cm suggests moderate climate, followed by development of an unaltered loess horizon (~640 to ~600 cm depth; C horizon) suggesting arid/dry climatic conditions with relatively higher wind velocity. Occurrence of a well-developed palaeosol (600 to 450 cm) suggests prevalence of warm/wetter climatic conditions. Cambisol deposited with high CaCO₃ content followed by a weakly developed palaeosol (450 to 200 cm) suggests dominance of cold/dry climate conditions and progression of the climate during the latter phase. Subsequently, the accumulation of parent loess ceased at ~14.7 ± 5.4 ka and the sedimentary environment was overtaken by the fluvial activity probably caused by widespread precipitation and/or glacial melting.

陆地黄土古土壤序列（LPS）是最广泛的古气候档案，记录了响应于冰川（冷干）和冰川间（暖湿）相的动态沉积过程。在本研究中，我们提供了喜马拉雅西部克什米尔山谷600厘米LPS露头的年代地层和古环境意义。光学激发发光（OSL）测年表明，在最后〜65.8±7.2 ka到〜14.7±5.4 ka期间，厚度可变，母黄土层位和经成因改良的黄土的多环古土壤单元发育。多代理分析显示了四个主要气候阶段，盛行时间介于65.8±7.2 ka至14.7±5.4 ka。约800至〜640 cm的沉积物沉积表明气候温和，随后黄土层位未发生变化（约640至〜600 cm深度；C层），表明干旱/干燥的气候条件具有相对较高的风速。发达的古土壤（600至450厘米）的发生表明温暖/较冷的气候条件盛行。坎比索沉积高钙₃含量，然后是较弱的古土壤（450至200 cm），这表明冷/干燥气候条件占主导地位，而后期则是气候变化。随后，母体黄土的堆积在〜14.7±5.4 ka处停止，沉积环境被可能由广泛的降水和/或冰川融化引起的河流活动所取代。
