Loess-paleosol sequences in the arid central Asia (ACA) provide valuable material for evaluating the evolution of paleoclimate and dust circulation in the Northern Hemisphere. However, determination of loess chronology has yet remained a main obstacle for paleoclimate interpretation. In this study, analyses of relative paleomagnetic intensity (RPI) were conducted in a loess section on the northern piedmont of the Tianshan Mountains covering the period since the last interglacial. The RPI record was found to be generally comparable with other recognized RPI stacks, confirming a globally consistent variation of the geomagnetic dipole field. Based on the RPI age model, the attempt to achieve paleoclimate assessment gives rise to largely similar variations to the North Atlantic records. Consequently, these results suggest that the RPI correlation could serve as a promising way to evaluate the age control of loess in the ACA. Nevertheless, in consideration of the complicated topography and loess deposition very close to the dust source, four main factors including carbon contamination, the reliability of luminescence signals, in situ depositional processes and complexity of remanence acquisition, may possibly contort the chronological determination in the ACA loess. Thus, cautions are still indispensable for paleoclimate interpretation with any solely chronological model and more work is therefore required to achieve a comprehensive understanding of loess chronological setting in this area.

干旱中亚（ACA）的黄土古土壤序列为评估北半球古气候和尘埃循环的演变提供了有价值的材料。然而，黄土年代学的确定仍然是古气候解释的主要障碍。在这项研究中，在天山北麓的一个黄土区进行了相对古地磁强度（RPI）的分析，涵盖了自上次间冰期以来的时期。发现RPI记录通常与其他公认的RPI堆栈具有可比性，从而确认了地磁偶极子场的全局一致变化。基于RPI年龄模型，实现古气候评估的尝试引起了与北大西洋记录大致相似的变化。所以，这些结果表明，RPI相关性可以作为评估ACA中黄土年龄控制的有前途的方法。然而，考虑到复杂的地形和非常接近粉尘源的黄土沉积，包括碳污染，发光信号的可靠性，原位沉积过程和剩磁获取的复杂性在内的四个主要因素可能会扭曲ACA中的时间顺序确定。黄土。因此，对于任何单一的年代学模型而言，对于古气候解释仍然是必不可少的，因此需要更多的工作来全面了解该地区的黄土年代学环境。考虑到复杂的地形和非常接近粉尘源的黄土沉积，包括碳污染，发光信号的可靠性，原位沉积过程和剩磁采集的复杂性在内的四个主要因素可能会扭曲ACA黄土的时间顺序测定。因此，对于任何单一的年代学模型而言，对于古气候解释仍然是必不可少的，因此需要更多的工作来全面了解该地区的黄土年代学环境。考虑到复杂的地形和非常接近粉尘源的黄土沉积，包括碳污染，发光信号的可靠性，原位沉积过程和剩磁采集的复杂性在内的四个主要因素可能会扭曲ACA黄土的时间顺序测定。因此，对于任何单一的年代学模型而言，对于古气候解释仍然是必不可少的，因此需要更多的工作来全面了解该地区的黄土年代学环境。
