摘要
本文简要介绍了航空大地电磁法原理、测量系统、倾子总散度、总相位旋转参数及二维、三维反演等;利用正演程序,计算了横向电性异常体倾子响应,结果表明倾子资料对横向电性分界面反映明显;最后结合实际地质情况,利用实测倾子及反演电阻率资料,推断解释了区内岩体、控矿构造的分布特征。实际应用表明,航空大地电磁法在探测断裂、岩体等方面具有较好的效果。
This paper briefly introduces the principle of aeromagnetotelluric method,the measurement system,the calculation of tiltepper parameters and the two-imensional and three-dimensional inversion.By using the forward program,the tipplter parameters of the geoelectric model of the transverse electrical interface were calculated.The results show that the tilter data obviously reflect the transverse electrical interface.Finally,combined with the actual geological situation,the distribution characteristics of rock mass and ore-control structure in the area were found by using the measured tilter and inversion resistivity data,and some results were obtained,which verify the feasibility of the method.
