The nature and origin of gleyed polygenetic paleosols in the loess covered glacial drift plain of Northern Missouri, USA

Description :
At 4 study sites in northern Missouri the Farmdale and Sangamon paleosols, which are developed in loess, are welded to the underlying Yarmouth paleosol, developed in till. Upon initial examination, however, they appear to be a single, thick, continuous gleyed horizon (gleysol). This paper presents geomorphic observations and lithologic data pertinent to the nature and genesis of these unique paleosols. Their behavior, coupled with the remarkable homogeneity within the solum, indicates that these soils underwent significant mixing, primarily by pedoturbation, a characteristic of modern vertisols.
