This data article associated with the manuscript "Magnetic mineral dissolution recorded in a lacustrine sequence from the Heqing Basin, SW China, and its relationship with changes in the Indian monsoon". Through detailed rock magnetic measurements, magnetic properties of the lacustrine sediments (magnetic mineralogy, their concentration and domain state) were clarified. Then, analyzing the relationship between magnetic property and paleoenvironmental proxies can reveal the paleoenvironmental implications of magnetic parameters of lacustrine sediments from the Heqing basin. Comparing paleoenvironmental proxies of lacustrine sediments from the Heqing basin with proxies associated with Indian monsoon recorded in Arabian Sea, and Bay of Bengal, can deepen our understanding about the characteristics of Indian Monsoon in the geological time.
本文数据与论文《中国西南鹤庆盆地湖相层序记录的磁性矿物溶解及其与印度季风变化的关系》相关。通过详细的岩石磁学测量，明确了湖相沉积物的磁性特征（磁性矿物学、其浓度和畴态）。然后，分析磁性特征与古环境指标之间的关系，可以揭示鹤庆盆地湖相沉积物磁性参数的古环境意义。将鹤庆盆地湖相沉积物的古环境指标与阿拉伯海和孟加拉湾记录的与印度季风相关的指标进行比较，能够加深我们对地质时期印度季风特征的理解。
