XRF core scanning, TOC, CN, 13C, and macro-charcoal counts from a fresh water mountain lake (Cueifong Lake), northeastern Taiwan@en

The dataset comprises X-ray fluorescent (XRF) core scanning, TOC, C/N, δ13Corg, and macro-charcoal counts of bulk sediment from the sediment core CFL-3. The purpose of this dataset is to reconstruct the sedimentation environment change after the large-scale deforestation. The lake sediment core CFL-3 was taken in Cueifong Lake, northeastern Taiwan in 2017, with a Russian Corer set. The XRF core scanning signals were normalized as described in Lin et al., 2023. The age model was established with 210Pb dating results, augmented by 137Cs dating results. The experiment and analyze detail were described Lin et al., 2023.本数据集包含采自中国台湾东北部翠峰湖的CFL-3沉积物岩芯的全样沉积物X射线荧光（X-ray fluorescent, XRF）岩芯扫描数据、总有机碳（Total Organic Carbon, TOC）、碳氮比（C/N）、有机碳稳定同位素δ¹³Corg及大炭屑计数数据。本数据集旨在重建大规模森林砍伐后的沉积环境变化。该CFL-3湖泊沉积物岩芯于2017年采用俄罗斯式岩芯钻采集完成。X射线荧光岩芯扫描信号按照Lin等（2023）的研究方法进行了归一化处理。年代模型基于铅-210（²¹⁰Pb）测年结果构建，并辅以铯-137（¹³⁷Cs）测年数据进行补充完善。实验与分析细节详见Lin等（2023）的研究成果。
