Abstract

The study area is situated at the southwest of Santa Cruz de la Sierra in the eastern Bolivian lowlands. Based on field observations, micromorphological analysis, geochemical and clay mineralogical data, 5 classes of paleosol horizons could be distinguished. The individual paleosol horizons as well as the sediments, in which they developed, were interpreted regarding their paleoenvironmental significance, taking into consideration the various controls on soil formation with particular focus on changes of local environmental conditions through time. Thus, 3 different pathways of soil formation were established. On the late Quaternary timescale, the results suggest a strong relation between paleoenvironmental conditions (climate, vegetation etc.), soil environment (soilwater flow, micro-environment) and the type of paleosol horizons developed in the study area
