Holocene Environmental Changes In Central Inner Mongolia Revealed By Luminescence Dating Of Sediments From The Sala Us River Valley, Sheng-Hua Li, Jimin Sun, Bo Li
Faculty of Science, Medicine and Health - Papers: part A
Luminescence dating of the fluvial and lacustrine sediments from the Sala Us River valley at the south edge of the Mu Us Desert, central Inner Mongolia, is reported. The study region lies in the northwestern marginal zone of the east Asian summer monsoon and is sensitive to climate change. The dating results combined with environmental proxies indicate that the Holocene Climate Optimum period, took place from 8.5 to 5 ka ago and was marked by lake development. After ~5 ka ago, the region became arid, as inferred from lake regression and fluvial activity. Deposition of fluvial sediments lasted from ~5 …
