Article on Abrupt shifts in dust sources has just been accepted!

A new paper on abrupt shifts in dust sources on the Chinese Loess Plateau has just been accepted into Quaternary Science Reviews. This work, led by Thomas Stevens at RHUL, details that there is a major dust source change around 20-21 ka. The data was collected using a multi-proxy approach, utilising optically stimulated luminescence, bulk sample geochemistry, heavy mineral analysis and grain-size analysis. This shift may be tied to abrupt climate change during the last glacial maximum and demonstrate the highly dynamic nature of the locations of dust generation during the last glacial period. 

Importantly, the evidence for an abrupt change in source also adds complexity to standard climate proxy analyses of loess using sediment properties.
