Through the comprehensive analysis on chronostratigraphy, sedimentology, and paleoenvironment of core GZoft-com:office:smarttags" />-2 in Wanqingsha area of the Pearl River delta, it is suggested that the Holocene sedimentation began from the depth of -15.37 m (about 6 kaBP); and strata below this level to the depth of -40.35 m belong to middle-late late Pleistocene with a maximum dating value around 43 kaBP, contemporaneous with the earliest deposit in the Pearl River delta. In the profile, two cycles of transgression-regression can be recognized:the middle-late late Pleistocene (consisting of 4 sub-cycles ) and the Holocene (consisting of 2 sub-cycles). It still has, in this area, fluvial-lake deposition facies during the lower sea level period of the Last Glaciation. The reconsruction of relative sea-level change curve of the Pearl River delta based on the multi-proxy index analysis indicates that the highest sea level period of the middle-late late Pleistocene was around 26～24 kaBP, and that of the Holocene was around 6～2.5 kaBP. The Late Quaternary paleoenvironment evolution in the Pearl River delta was obviously controlled by global paleoenvironment changes. oft-com:office:office" />
