东昆仑夏日哈木镍矿区AMT法深部勘探技术试验

Test on Deep Exploration Technology by Using the Audio Magnetotelluric Method in Xiarihamu Ni Deposit in Eastern Kunlun

为了研究夏日哈木镍矿区深部构造特征与电性特征,选择音频大地电磁测深(AMT)法在夏日哈木矿区开展深部勘探技术试验。首先,根据已知地质资料对勘探模型进行了二维正演模拟,然后对正演数据进行一维和二维反演,说明所选方法的有效性。最后将AMT法勘探试验结果地质成果资料对比,两者基本吻合,说明AMT法深部勘探技术试验取得了良好的应用效果。

In order to study the deep tectonic characteristics and electrical characteristics ol Xiarihamu Ni mine,deep exploration technology test has been carried out in Xiarihamu area by using the audio MagnetoTelluric sounding(AMT)method.First ol all,two-dimensional forward modeling ol the exploration model is carried out according to the known geological data,and the one-dimensional and two-dimensional inversion ol the forward data have been carried out to illustrate the effectiveness ol the selected method.Finally,the comparison between geological results and the AMT exploration results shows that the AMT method has achieved good application effect.
