摘要：

Field observations, physical properties, sorting coefficients, and homogeneity indicate that the silty mantle in Southeastern Pennsylvania is loess. The mantle's geographic location, gradation in thickness, and very fine sand content indicate that the Coastal Plain and the adjacent rivers are probable source areas for the loess.
