摘要
Based on the regional gravity-magnetic and topographic data of Nanjing Hengxi-xiaodanyang demonstration 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 comprehensive interpretation of geophysical exploration methods,it is very essential to carry out joint-inversion of geological anomalous body.It can effectively improve the interpretation accuracy of gravity magnetic.
