摘要
通过对南沙海域中建南盆地重磁资料的分析及反演计算,依据盆地的地质与地球物理特征,对地震资料难以解决的基底结构、性质进行了研究,确定了磁性基底与莫霍面深度,确定了地壳类型,并对盆地内的深部大断裂及磁性基岩属性作了推断,为今后的研究提供了依据。
According to the analysis and inverse calculation of gravity and magnetic data from the Zhongjiannan basin in the Nansha sea areas and also according to geologic and geophysical characteristics of the basin, the authors studied the basement structure and nature that are difficult to be studied by using seismic data, determined the depths of the magnetic basement and Moho, made clear the crustal types, and inferred the deep large faults within the basin and the attribute of the magnetic basement, providing basis for the future researches.
