Eolian dust mass accumulation rates(MARs) is crucial to rebuild paleoclimate of the dust source area and to evaluate the role of dust in paleoclimate change.Here we present the grain size composition of detrial sediment in one sediment core(cover the last 250 kyr) collected from the Benham Rise in the western Philippine Sea,and radiogenic strontium(Sr) and neodymium(Nd) isotopic compositions of three different grain size fractions(<5 μm,5-20 μm,>20 μm) in the detrital sediment of some core-top sediments in and around the Benham Rise.
