Abstract: Henglan area, Zhongshan area of the Pearl River Delta has special significance to research of the Qua-ternary strata in the region of the South China. The Henglan Formation of Holocene was defined due to its excel-lent representative of the area. Based on comprehensive analysis on lithologic feature, grain size and geochemical of the coreⅣ01 in Henglan area, the sedimentary characteristics in this area since the late Quaternary was stud-ied. It is suggested that since the Late Quaternary, there were three sedimentary cycles in the study area:one in the late Pleistocene and two in the Holocene. Because of the distinctive sedimentary environment of the Pearl River Delta, the sedimentary cycles of the delta were particular by the positive sequential patterns (the coarser sediments at lower layer and becoming finer upwards) of the Progradational delta. Based on the above research, the analysis of grain size and the trace elements contents of B, Ba and Sr in the sediments, the paper further dis-cussed the processes of transgression and regression since Late Quaternary in the study area. Three regres-sion-transgressions cycles could be recognized: the earliest transgression happened in middle-late Late Pleis-tocene, while the others followed until the Holocene. The latter two transgression, began about 7.5 ka B P, were separated by the regression appeared in middle-late middle Holocene (5~2.5 ka B P).
