中国海区及邻域地质—地球物理系列图

MAP SERIES OF GEOLOGY--GEOPHYSICS OF CHINA SEA WATERS AND ADJACENT AREAS (ON THE SCALE OF 1:2,000,000)

1959年5月,地质部提出并组织实现在中国海域内进行以油气为主的海洋地质工作,迄今已经整整三十年了.当时,我们对于在辽阔的中国海域内开展海洋地质工作选取了这样的途径:1.任务与方法(1)以地球物理方法为主要手段,结合进行表层取样和钻探,坚持进行地质一地球物理综合研究.(2)以油气资源勘查为主要目标,在区域普查的基础上,发现沉积盆地,并探索其含油气性.(3)以现代地球科学理论为指导,深入认识中国海域的地质特征,演化历史及其成因机制,发展海洋地质科学.在这三十年中,海洋地球物理装备和技术方法都得到了不断的发展和完善.最近十年内已经广泛使用.2.装备与技术(1)综合卫星导航(Mx—200B)与无线电定位系统(Argo和Maxiran),来实现对数据采集的位置测定与控制.(2)质子旋进磁力仪,进行海洋与航空磁测的数据采集.

Bureau of Petroleum Geology and Marine Geology began the map series of geology-geophysics of China sea waters and adjacent areas (on the scale of 1: 2,000,000) in 1986 and finished by the end of the first quarter of 1989. The appraisal of the results were made on 15-16 of august the same year in Beijing. The Appraisal Group set a high value on the map series and unanimously thought them as a great beginning in the field of marine geology and a summary of China's marine geologie work for the last three decades. The map series will be published soon and put on sale publicly in the world. The map extent is through 102?140 and 0-42N. The series consists of 9 maps: topographic map, geomorphologic map, air gravity anomaly map, Bouguer anomaly map, magnetic profile planimetric map, geologic map, geodynamic map, geotectonic map and distribution map of Cenozoic sedimentary basins. The first five are basic maps, mainly according to first-hand data from China sea areas; the last four are achievement maps, worked out under the guidance of plate geotectonic theory and through comprehensive interpretati'on of geologie and geophysical data.
