摘要
本文通过冲绳海槽地区已有的1∶50万布格重力异常数据,对冲绳海槽断裂构造进行了推断解释,据此分析了冲绳海槽地区的构造特征;以东海南地学重、磁、震联合解释剖面提供的莫霍面深度作为控制,采用频率域的Parker三维迭代界面反演方法,得到了全区的莫霍面深度,为研究冲绳海槽的地质构造提供了基础资料。
The fault structure of Okinawa was interpreted by the latest 1:500000 Bouguer gravity anomalies data in this paper, and the structure features of the Okinawa were analyzed. Parker iterative 3D inversion method of frequency domain was applied taking the depth of Moho surface from gravity, magnetic and seismic interpreted sections in the South East China as controlling conditions, so as to obtain the depth of Moho surface through the whole area. The results provided the basic data for the research on the geological structure of Okinawa trough.
