Abstract: Based on a multi-proxies study (including mineralogy, elemental geochemistry and pollen analyses) on Core SX97, which lies on the north flank of the Pearl River estuary, the authors suggest that the climatic and environmental evolution since 7000 a B.P.over the Pearl River Delta area could be divided into five stages.These stages between different climatic and environmental proxies, such as mineralogy, elemental geochemistry and pollen data, correlate very well with each other as well as with the climatic and environmental information over the coastal zone of South China that was recovered previously from the coastal dunes, beach-rocks and marine deposits.Then, the drainage response of the Pearl River to local climatic and environmental variations is explored.Core SX97 shows that the Pearl River drainage response sensitively to local climatic and environmental changes.When the climate over the Pearl River drainage was relatively warm and humid, weathering was relatively strong, relatively more iron was lost from the weathering profile, and better vegetation was developed over the drainage.All these would result in more FeO and Fe₂O₃, less herbal relative content, less quartz and more clay mineral (such as kaolinite, montmorillonite and illite) mass fractions in the estuary sediments.Contrary to this was the situation when the climate was relatively cold and arid.
