地质部系统各水文地质单位近一、二年来,陆续开展了第四纪地质研究课题,并取得了一定的成果。如江苏二水对淮北地区第四纪地层划分与对比进行了较为系统的总结;辽宁、浙江队编制了全省第四纪地质图,江苏一水在对长江三角洲第四纪地质研究工作中,与中科院海洋所等单位协作,完成了1/50万三角洲地区第四纪地质图和1/20万南通沿海第四纪地质图的编制工作;黑龙江一水初步确定了黑龙江省第四系下限深度,认为第四系内存在九套地层,并首次获得了白土山组地层的年龄,为编
Geological Department of the hydrogeology units nearly a year or two, one after another carried out Quaternary geological research topics, and achieved some results. For instance, the Quaternary stratigraphic division and contrast in Huaibei area of Jiangsu Ershui have been systematically summarized. The Quaternary geological map of the province has been prepared by Liaoning and Zhejiang teams. In a study of Quaternary geology in the Yangtze River Delta, In collaboration with the Institute of Oceanology and other units of the Chinese Academy of Sciences, the quaternary geologic map of 1/50 million deltas and the Quaternary geological map of 120,000 Nantong coastal areas were completed. The depth of the Quaternary lower limit of Heilongjiang Province , That Quaternary within nine sets of strata, and for the first time won the Clay group of strata age, for the series
