Abstract：
The dataset is developed based on Chaona lake sediment core located in the western part of the Loess Plateau. A series of 970-cm sediment cores which were recovered from the lake basin using by a piston corer equipment in 2016. The data of chemical elements and magnetic susceptibility was determined at 0.1-0.5 cm resolution using X-ray fluorescence (XRF) core-scanning measurements. Based on a robust chronology sequence that was established by a multiple dating approach and high-resolution, continuous elemental geochemistry and magnetic susceptibility records, a sedimentological and geochemical reconstructions of environment and climate variations spanning the Middle-Late Holocene was conducted. The dataset includes: (1) the geo-location of sediment core; (2) the age sequence of a lake core on the Loess Plateau over the past 6000 years; (3) the variation of the major elements (Al, Si, S, K, Ca, Ti, Mn, Rb, Sr, Br and Fe) in lake core over the past 6000 years; (4) the variation of element ratios (Si/Ti and Rb/Sr) in lake core over the past 6000 years; (5) the variation of the magnetic susceptibility in lake core over the past 6000 years. The temporal resolution of the element and magnetic susceptibility data is 10 years. The dataset is archived in .shp and .xlsx formats, and consist of 9 data files with data size of 86.8 KB (Compressed into one file with 84.6 KB). The analysis paper based on this dataset has been published in Palaeogeography, Palaeoclimatology, Palaeoecology, Issue 644, 2024.
