| 摘 要： | 重力场数据处理涉及的内容一般有场的延拓、方向导数以及局部场、背景场分离提取等,它们均属于重力异常分离问题的范畴。而重力场视密度三维反演技术是根据重力异常求取和确定场源体视密度的三维分布,其视密度分布图与地层岩性、地质构造以及地下矿体直接关联。对姚家岭地区重力场视密度三维反演技术的应用结果表明,视密度分布图对区内不同岩性地层的分布、褶皱和坳陷构造的分布特征等地质现象取得了良好的应用效果。

| Abstract: | Gravity field data treatment involves in the filed continuation, directional derivative, separation and extraction of local and ambient field, which all belong to separation of gravitational anomaly. Three-dimension apparent density inversion of gravity field is a technology to determine 3D distribution of apparent density of the field source, and the apparent density distribution map directly corresponds to stratigraphic lithology, geological structures and underground ore bodies. The inversion results for the Yaojialing area indicated that the apparent density distribution map well reflected the distribution of strata of different lithology, folds and depressions in the area. |
