摘要
本文重点研究东海盆地新生代沉积物中微量元素、孢粉和重矿物资料,推测了新生代时东海盆地及其周围古地貌的变化,並推断古长江碎屑物在中中新世晚期时才开始进入东海盆地。
This paper studies the data of microelements, palynology and heavy minerals in the Cenozoic sediment of the East China Sea basin and assumes the paleogeomorphologic change in the basin and its adjacent areas in the Cenozoic Era. Further more, the authors infer that the clastic material of the ancient Yangtze River initially entered the basin in the later period of mid-Miocene.
