Karakul lake is the distal proglacial lake of the Muztagh Ata glaciers in Xinjiang, and its material input is mainly affected by glacier changes. The Karakul lake sediment core was drilled in the deepest part of the Karakul Lake (38 ° 26.56 ′ N, 75 ° 03.65 ′ E, water depth of 19m) in June and July, 2013, by the research group of prof. Xubaiqing, Institute of Tibetan Plateau Research. The length of the sediment core was 14.16m. This data set is the geochemical data of the lake sediment core, providing high-resolution (0.2mm) information of geochemical elements' contents. The element data was obtained using the nondestructive X-ray fluorescence (XRF) measurements (Itrax Core Scanner, Sweden). The measurement was performed in the Key Laboratory of Tibetan Environment Changes and Land Surface Processes, Chinese Academy of Sciences. The element content in this data set changes obviously, among which the Zr element, Zr/Rb ratio and Rb/Sr ratio provides the long-term glacier change history in Muztagh Ata region, while Ti element provides the dust change history. These data are of great scientific significance for studying the long-term paleoclimate and environmental change histories in the the westerly-dominated region.
