The objective of this study was to determine the physical, chemical, micromorphological, and mineralogical characteristics of white clay soils as they relate to pedogenesis. Three representative pedons in the Three River Plain, Heilongjiang Province were selected for this study. The ratios of Ti/Zr and Zr/Sr in silt fractions were used to evaluate parent material uniformity. Trace elements including rare earth elements (REE) were analyzed by instrumental neutron activation analysis. Sr, Ti, and Zr were determined by x-ray fluorescence. Clay minerals were identified by x-ray diffraction analysis. Micromorphology of the soils was based on petrographic examination of thin sections.

520 $a Lessivage, periodic reduction-oxidation change, continuous addition of mica to the surface from aerosolic dust, and accumulation of organic matter were responsible for pedogenic characteristics of the soils of this study. The soils of this study were classified as Planosols in the FAO-UNESCO system and Boralfic Argialbolls in U.S.D.A. Soil Taxonomy. (Abstract shortened by UMI.).
