Late-Quaternary dynamics and palaeoclimatic implications of an alluvial fan-lake system on the southern Alxa Plateau, NW China

Alluvial fan-lake complexes are common in the piedmont zone of mountains on the southern Alxa Plateau, NW China. Interconnected by the erosional and depositional processes, they can be treated as a typical source-to-sink system. Yet the dynamics of these coupled sedimentary systems during the Late Quaternary is poorly understood. For example, radiocarbon dating of alluvial fans and elevated shoreline features of megalakes in this area usually...
