Holocene pollen, charcoal, and geochemical proxy data from HEIHE and TAHE profiles, Northeast China

This dataset contains pollen percentages, charcoal concentration, and geochemical proxy data (pH, magnetic susceptibility, and grain size) from HEIHE and TAHE sediment profiles in Northeast China, covering the Holocene.本数据集包含中国东北地区黑河（HEIHE）与塔河（TAHE）沉积物剖面的花粉百分含量、炭屑浓度及地球化学代用指标数据（pH值、磁化率（magnetic susceptibility）、粒度（grain size）），其时间跨度覆盖全新世（Holocene）。
