琼东南盆地基底结构综合地球物理研究

通过对琼东南盆地重磁资料的平面与剖面分析处理和正反演计算,依据盆地地质、地球物理特征.采取了针对性的综合地球物理研究思路和解释方法,对地震资料无法解决的琼东南盆地基底结构进行了研究,确定了盆地的重力和磁性基底深度,并对盆地内的断裂展布和局部异常作了划分和分析解释,提出了新的认识,为今后进一步研究提供了依据.

COMPREHENSIVE GEOPHYSICAL RESEARCH ON THE BASEMENT STRUCTURE IN QIONGDONGNAN BASIN

Based on the analyses, processing and the forward/inverse calculation of the plane and section gravity and magnetic data in Qiongdongnan Basin, the and in accordance with the actual geological and geophysical characteristics of the basin,authors have taken effect measures including the research guiding principles and the interpretation methods to have a detailed study of the basement structure of the basin which couldn't be clearly interpreted by the obtained seismic data. The authors also put forward some new understandings including the gravity and magnetic basement depth,fault behavior and local anomaly attribute, which make a foundation for the further research work.
