山东桃村地区沉积岩、岩浆岩、变质岩发育,构造断裂特征显著,可以得到磁法、地震、电法的地球物理特征,针对该区不同地质年代、不同物质成分与结构的岩层之间所具有的磁性、速度、电性等差异的特性,可用地球物理方法进行获取。对获得的数据,先对磁法、地震、电法数据逐项的进行处理分析,得到了地层和断裂的异常特征在三种不同剖面上的具体表现。然后对三种地球物理数据进行综合对比分析,进一步精细标定了工区内断裂边界,取得了明显的应用效果。
Geological features of magnetic, seismic and electrical methods are obtained in sedimentary rocks, magmatic rocks and metamorphic rocks in the Taocun area, Shandong Province. The characteristics of tectonic faults are obvious. According to the geophysical characteristics of different geological compositions and structures Magnetic, speed, electrical and other differences in the characteristics of available geophysical methods to obtain. For the obtained data, the data of magnetic method, seismic data and electrical data are processed and analyzed item by item first, and the concrete manifestation of abnormal features of strata and faults on three different sections is obtained. Then, the three kinds of geophysical data are comprehensively compared and analyzed, and the fracture boundary in the work area is further finely calibrated, and the obvious application effect has been achieved.
