摘要:
选定东大别局部地区(30.5°～32.0°N,116.0°～117.3°E)为研究区域,结合地质、地形数据、初始磁化率建立三维模型,并以该区域内的航磁模型为磁测数据,运用ModelVision Pro软件进行多次迭代反演,从而得出研究区深部磁异常的分布、深度以及形态。通过对模型计算结果与原始数据进行对比,可以清晰地辨别出郯庐断裂带以及东西走向的秦岭—大别造山带在研究区内的大体位置及走向,且秦岭—大别造山带呈负异常区域以及郯庐带两侧的正异常区域与实测模型都较吻合; 区别较大处位于研究区北部边界,实测数据呈正
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.
