对我国浅海及大陆第四纪地层的对比研究,我们选择了南黄海陆架区及其沿海平原作为第一阶段的工作区.1983年秋和1984年春夏,在南黄海水深30—50米之间施工了三个深度分别为114.60米、109.22米、32.93米的三个取芯完整的钻孔.在苏北平原沿海施工了两个深度为402米及460米的达到基岩的钻孔,1984年冬,又在南黄海完成了1145公里的浅层地震地层剖面测量、旁侧声纳扫描及测深为内容的浅层地球物理调查及柱状样、表层样、古生物及底栖微体生物活体取样等为内容的浅层地质调查.研究范围是E124°15′以西,N32°12′至34°56′之间的海域(图 1).本文以海上调查资料为主,结合海上钻孔的部分资料,对南黄海陆架上部沉积及其环境演变的若干问题进行初步探
For the comparative study of Quaternary stratigraphy in China’s shallow sea and the mainland, we chose the South Yellow Sea shelf area and its coastal plain as the first stage of work area. In the autumn of 1983 and spring and summer of 1984, in the South Yellow Sea, the depth of 30-50 meters Three complete coring cores were drilled at depths of 114.60 m, 109.22 m and 32.93 m, respectively. Two drilling holes reaching the basement at depths of 402 m and 460 m were constructed along the coast of the Northern Jiangsu Plain. 1984 In winter, another 1,145 km of shallow seismic stratigraphic profilometry, side sonar scanning and sounding were carried out in the southern Yellow Sea to investigate the shallow geophysical survey, as well as columnar samples, surface samples, paleontology and benthic organisms Sampling, etc. The study area is the sea area between west of E124 ° 15 ’and N32 ° 12’ to 34 ° 56 ’(Figure 1) .In this paper, based on the marine survey data, combined with the offshore drilling Some of the data on the South China Sea shelf sediment deposition and environmental problems of some of the initial exploration
