High-frequency East Asia monsoon variability during 115000-93000 a BP in Northern China
The FGS5c-d segment of the Fanjiagouwan section is located in the Salawusu River Valley on the southeast margin of the Mu Us Desert in China. It contains 17 sedimentary cycles consisting of aeolian dune sands and lacustrine facies during 115000 - 93000 a BP. Analyses of grain size and trace geochemi...
