摘要
本文根据近年工程钻探剖面及^(14)C测年资料,对榕江断陷的形成。演变进行讨论,认为该断陷开始形成于35000年前,完成于23000年前,并认为前人所指莲塘、桑浦山南麓的第三,第四两级“海蚀”遗迹(阶地)不是海蚀成因,而可能是风蚀产物。
According to the recent engineering probing profile and the detected data of 14C, the form and evolution of Rongjiang rift are discussed in this paper. It thinks that this rift began to form before 35000 years and finished before 23000 years. It also holds that the traces of sea erosion at the third and the fourth stage of Liantand and the south of Sangpushan which pointed by predecessors are not caused by the sea erosion, but may be the products of wind erosion.
