文献[1]曾报道过DDT测年法在长江口～东海陆架区开阔海域进行沉积物测年的研究成果。为了探讨DDT测年法在近岸河口港湾进行现代沉积物测年的可能性,本文再报道最近在厦门外港区所取四组岩芯柱样的初步测年结果。
Literature [1] has reported the DDT dating method in the Yangtze River Estuary ~ East China Sea shelf area open sea dating sediment dating results. In order to investigate the possibility of DDT dating in modern sediment dating near the estuarine estuary, this paper reports the preliminary dating results of four sets of core-column samples recently taken in the outer harbor area of Xiamen.
