文摘

Heavy mineral analysis of lacustrine sediments enabled distinguishing different provenance areas of the aeolian transported dust Marked changes in the aeolian activity are indicated at the transition of the Heinrich 2 Changes between easterly and westerly winds are indicated during the period 23,000 to 20,000 b2k Aeolian activity and changes of the heavy mineral assemblage display a close correspondence to varve thickness
