Abstract: Clay minerals in 15 surficial samples and 5 profile samples from the Yangtze Delta plain were analyzed by X-ray diffraction. The result shows that clay mineral assemblage of the surfical sediments are distinguished by the coastline 7500-8000aBP, indicating different sediment sources and sedimentary environments. The change of content of illite vs. kaolinite in the profile sediments reflects the climate fluctuations since late Pleistocene.

Key words: spatial and temporal distribution, paleoenvironmental implication, Yangtze Delta plain, clay minerals, spatial and temporal distribution, paleoenvironmental implication, Yangtze Delta plain
