摘要 河北南部石炭、二叠纪煤系中发育了多种类型的古土壤.通过露头剖面宏观特征的观察描述,并系统采样后,在室内进行了地球化学黏土矿物分析.依据所观察到的宏观特征和地球化学、黏土矿物在古土壤剖面上的变化特征,共识别出6种类型古土壤.根据Nettleton等关于古土壤的分类方案,这6种古土壤分别为古始成土、古有机土、古氧化土、古变性土、古灰化土和古旱成土. Many kinds of paleosoils develop in the coal measures of Carboniferous and Permian in southern Hebei, China. Six kinds of paleosoils are identified based on the observation of outcrops in field and the geo-chemical analyses and the clay mineralogical analyses of samples in laboratory. According to Nettleton et al' s classification of paleosoils, the six kinds of paleosoils are Paleoinceptisol, Paleohistosol, Paleooxisol, Paleoverti-sol, Paleopodsol and Paleoaridisol separately.
