摘要：

Three pedons each of Clermont (Typic Glossaqualfs) and Avonburg (Aeric Fragiaqulfs) soils were investigated on the Illinoian till plain of southwestern Ohio in order to evaluate parent material stratigraphy and to determine if paleosols were substantially altered following burial by a thin mantle of loess. The relationship between fragipan development and paleosol properties was also examined. The soils were found to have formed in 57 to 69 cm of Late Wisconsinan (Peoria) loess overlying a composite Early Wisconsinan and Sangamon paleosol. The Sangamon palesol, which was most strongly developed at approximately 150 to 200 cm, was formed in Illinoian till.
