A micrornorphological approach, based upon sets of closely-spaced thin sections taken from three sites located along a climatic and depositional gradient, has been utilised to reconstruct the sequence of pedogenic and sedimentary events leading to the development of the S1 paleosol in northwest China. Two main pedosedimentary stages related to regional changes in monsoonal controls are evident at...
At four 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). Along flat tabular drainage divides this welded solum is gleyed and is identical in all respects with the historical definition...
