- Abstract:
- Part area of eastern Dabie mountain is selected as the research region(116.0°～117.3°E,30.5°～32.0°N).Combined with the geological and topographic data,three-dimensional model was established by the initial magnetic susceptibility.Using the aeromagnetic model of this area as the magnetic survey data,we applied the ModelVision Pro software for multiple iterative inversions to obtain the distribution,depth and the form of magnetic anomaly in the deep part of the research area.Comparing the model calculation results with the original data,we can see clearly the Tancheng-Lujiang fault zone with NNE trending and the Qinling-Dabie orogenic belt with EW trending.The latter shows negative anomalies,and the positive anomalies at the both sides of the former fault agree well with the actual measurement model.The big difference appears at the north boundary of the research area.The actual measurement data show positive value while the calculation model shows negative value in this area.
