- Abstract
The article discusses the study on numerical modeling and field-based calibration of desert pavement. In this study, a numerical model based on the classic conceptual model in which pavements co-evolve with their underlying eolian epipedons over millennial timescales is developed. It conducts a surficial geologic mapping and pavement sedimentological analysis on two desert piedmonts. The study provides a rigorous calibration of pavement formation rates in the study areas and provides evidence supporting the use of pavements as local relative surface-age indicators over Holocene to late Pleistocene timescales.
