The drilling of ZKC1 borehole was carried out at Lianghucun in southeastern Anxiang sag.  According to the idea that the chemical weathering index (CWI) of terrestrial sediments has a positive correlation with temperature and humidity and that the magnetic susceptibility has a negative correlation with temperature and humidity, the authors probed into the Quaternary climate evolution of the Dongting basin. The climatic evolution process coincides basically with climatic change indicated by sporopollen assemblages of the core from the ZKC1 borehole, and also accords with Quaternary climatic variations of eastern China, which suggests that the CWI of the sediments shows a good response to the Quaternary climate evolution.
