The past 360 kyr high-resolution particle size and magnetic susceptibility data of Taixian loess from the central Chinese Loess Plateau (CLP)

Our studied site, Taixian in the central CLP (35°38´ N, 109°16´E), preserved a relatively perfect loess-paleosol sequences with distinctive stratigraphic markers. We have collected 746 samples spanning from the Holocene S0 (S represents paleosol layers) to the mid-Pleistocene L4 (L indicates loess layers), with at about 2 cm sampling resolution above 3 m and 4 cm intervals at the 3-27 m in depth. We have measured the magnetic susceptibility (MS) and bulk grain size data of this section in the laboratory.

本研究的采样点位位于黄土高原（Chinese Loess Plateau, CLP）中部的台县（Taixian），地理坐标为35°38′N，109°16′E。该剖面保存有相对完好的黄土-古土壤序列（loess-paleosol sequences），且赋存特征鲜明的地层标志层（stratigraphic markers）。本次研究共采集746件样品，层位覆盖全新统S0（S代表古土壤层）至中更新统L4（L代表黄土层）；其中3米以浅地层的采样分辨率约为2 cm，3~27米深度区间的采样间距为4 cm。我们已在实验室完成了该剖面的磁化率（magnetic susceptibility, MS）与全样粒度数据测试。
