摘要: 基于南京横溪-小丹阳示范区区域重磁数据、CSAMT和地形、地质资料,并综合区内物性特征,建立了初始地质-地球物理模型。在地质、钻孔资料的约束下,利用重磁电数据处理与反演软件系统,对区内典型重力、磁法、电法测线数据进行综合物探联合反演,通过不断修改地质-地球物理模型,使重、磁正演拟合数据和实测异常数据达到最佳拟合状态。结果表明,利用多种物探方法相互验证和综合解释方法,开展地质异常体的联合反演,能有效提高重、磁解释精度。

Abstract: Based on the regional gravity-magnetic and topographic data of Nanjing Hengxi-xiaodanyang demon-stration area, integrate physical properties, an initial geologic geophysical model is established. In the constraint of geology and drilling data,using gravity magnetic resistivity data processing and inversion software system, we did the integrated geophysical joint-inversion for a typical gravity magnetic electrical line data of the area. By continually modify the geologic geophysical model, made the gravity magnetic forward data and measured data to achieve the best fitting condition. The results show that, by using multiple mutual authentication and compre-hensive interpretation of geophysical exploration methods, it is very essential to carry out joint-inversion of geo-logical anomalous body. It can effectively improve the interpretation accuracy of gravity magnetic. -
