High‐resolution records of climate change in arid eastern central Asia during MIS 3 (51 600–25 300 cal a BP) from Wulungu Lake, north‐western China
ABSTRACT Detailed records of climate change during the Last Glaciation in arid central Asia are scarce. Here we present a sedimentological and geochemical record from Wulungu Lake in north‐western China, providing the first high‐resolution, continuous sedimentary records in this region covering Mari...
