近三年来,我们在珠江三角洲打了66个钻孔,采集了489个第四系样品。对其中24个钻孔的34个岩芯样品和8个浅层样品作了C~(14)年龄测定。经分析研究,对珠江三角洲的形成年代,有了一些新的认识。现加以论述如下。一、前人对珠江三角洲形成年代的推论以往由于缺乏C~(14)测年数据,对珠江三角洲的形成年代,人们只是作一般的推论,
In the past three years, we have drilled 66 holes in the Pearl River Delta and collected 489 Quaternary samples. C 14 age determination was performed on 34 core samples and 8 shallow samples from 24 boreholes. After analysis and research, there are some new understandings on the formation of the Pearl River Delta. Now to be discussed as follows. First, predecessors’ corollary to the formation of the Pearl River Delta In the past, due to the lack of C ~ (14) dating data, people made only general inferences about the formation of the Pearl River Delta.
