为配合珠江三角洲综合整治规划,我所地貌室与广东省水文地质二队等单位协作,正在开展《珠江三角洲的形成发育和演变规律》的研究。该课题以年代学为中心,探讨珠江三角洲的形成过程和沉积速率。目前,钻探工作初步告一段落,取得的几百个岩芯样品正在分析鉴定。其中取自东莞县石排公社下沙大队PK5号钻孔的腐木层(埋深15米),经中国科学院贵阳地球化学研究所作C~(14)测定,为37,000±1,480年;取自新会县
In line with the comprehensive planning for the Pearl River Delta, the Meteorological Office of China cooperates with units such as the Second Hydrology and Geology Team of Guangdong Province and is carrying out a study on “the law of the formation and evolution of the Pearl River Delta.” The subject of chronology as the center, to explore the Pearl River Delta formation process and sedimentation rate. At present, drilling has come to an initial stop and several hundred core samples obtained are being analyzed and identified. Among them, the rotten wood layer (depth 15 meters) taken from No. PK5 of Xiasha Brigade in Shek Pai Commune of Dongguan County was measured by C ~ (14) of Guiyang Institute of Geochemistry, Chinese Academy of Sciences to be 37,000 ± 1, 480 years; county
