摘要: 从粒度参数(Mz、δ1、SK1和Kg)、频率曲线、累积曲线、概率值累积曲线、δ1-Mz散点图以及粘土矿物和孢粉分析等方面,探讨了前人作为冰碛的粘土砾石层,其特征与冰碛物或粘土泥石流不同,实为亚热带湿润气候下山洪搬运的洪积锥或洪积扇沉积物.

Abstract: According to the analyses of grain size parameters(Mz,δ1,SK1 and Kg),frequency curve, accumulative curve, probability accumulative curve, δ1-Mz discrete map, claymineral and sporo-pollen,etc., the Quaternary boulder clay, which was considered asterminal moraine by S. J. Lee in 1936,are studied in this paper. The research resultsshow that the characters of the boulder clay deposits are different from glacial moraine and debris flow. The boulder clay deposits are really a flood deposlits of pluvial fan in subtropic humid climate and not a moraine deposits in cold glacial climate.
