Chemical properties; sand, silt and clay mineralogy; and particle size distributions are compared and found to support the concept that Lexington, Wellston, Bewleyville, and Dewey soil series were developed in wiedly different residua overlain by a rather uniform loess mantle. Data presented indicate greater weathering of the loess mantle when it is underlain by coarser textured residual material as well as illuviation of materials from the loess mantle into and/or through the coarse textured residuum. Thinner loess overlays tend to exhibit significant mixing with underlying materials from the residuum.
