摘要：Tracing the provenance of aeolian sand in deserts is essential for understanding the mechanisms behind desert formation and sediment transportation processes. There are multiple sand belts that interconnect major deserts within the Alxa Plateau of northern China, observed from satellite images and field research. However, the aeolian sand transport from the Badain Jaran Desert (BJD) to the Yamalik Desert (YD) and Ulan Buh Desert (UBD) through these expanding sand belts is still being underestimated. In this study, we analyzed the content of trace metals and Sr-Nd isotopic compositions in the ? 2023, The Authors. All rights reserved.
