More and more evidence indicates that the onset of the East Asian(EA) monsoon can be traced back to the Oligocene-Miocene boundary(at about 23 Ma).However,the process of its evolution is still less well-known until *** we investigate its late Neogene evolution by analyzing a terrestrial mollusk sequence,from the Chinese Loess Plateau(CLP),covering the period between 7.1 and 3.5 *** the modern ecological requirements of these organisms,we were able to define two groups of cold-aridiphilous(CA) and thermo-humidiphilous(TH) species,representing the EA winter and summer monsoon variations, respectively,as previously defined in the Quaternary glacial-interglacial *** in these two groups indicate two different monsoon dominated periods during 7.1-3.5 ***,between 7.1 and 5.5 Ma, the EA winter monsoon,with a 100-kyr periodicity,was ***,between 5.1 and 4 Ma,the EA summer monsoon dominated,with a 41-kyr ***,our mollusk record yields valuable evidence for a late Miocene-Pliocene transition of about 400 kyr from winter monsoon dominated towards summer monsoon dominated,associated with a periodicity transition from weak 100 kyr to 41 *** strengthened winter monsoon interval,with a 100-kyr periodicity,is coeval with orbital-scale global icevolume changes,in conjunction with the uplift of the Tibetan Plateau which probably reinforced the winter monsoon ***,closures of the Panama and Indonesian seaways,associated with changes in obliquity between 5.1 and 4 Ma,are probably major forcing factors for the observed dominant summer monsoon with 41-kyr frequency,favoring heat and moisture transports between low and high latitudes to allow TH mollusks to grow and develop in the CLP.
