Abstract: Based on a high resolution grain size, clay minerals and AMS¹⁴C dating analysis of core MJK16 from the south of Minjiang Estuary, we attempt to reveal the provenance and paleo-environmental evolution of Minjiang subaqueous delta since the middle-late Holocene. During the high sea level period of the middle Holocene(7—4 ka BP), Meihua Branch may be the main channel for the transportation of terrigenous materials to the south of Minjiang Estuary. The sediment dominated by sand ［(58.6±8.7）%］ with a mean grain size of （3.76±0.49） φ. In addition, more Yangtze River terrigenous materials were transported to the Minjiang Estuary by enhancement of Zhejiang-Fujian coastal current, resulting in the increase of smectite content in sediments. However, the sea level decreased slightly and Meihua Branch degraded during the late Holocene(3 ka BP). The sediment in the southern of Minjiang Estuary was mainly silt ［(58.1±4.4）%］, and the mean grain size was （6.30± 0.32） φ, which was similar to fore-delta sedimentary environment. In the late Holocene, the content of smectite in the sediments of Minjiang Estuary decreased significantly caused by the weakening of Zhejiang-Fujian coastal current meanwhile the content of kaolinite from Minjiang increased.
