| 摘 要： | 应用可控源音频大地电磁法,在河南新安县石寺—北冶铝土矿区进行隐伏铝土矿勘查。结果表明,利用该方法能够反演奥陶系灰岩古地形界面,推断铝土矿含矿岩系的赋存空间,预估算铝土矿潜在资源量;该方法探测深度较大,能满足深部铝土矿勘查需要;根据可控源方法断面电阻率等值线,可较清晰反映地层的产状,进而根据电阻率值划分地层。

| Abstract: | The CSAMT method was used to conduct exploration of concealed ore bodies in the Shishi-Beiye ore district of Xin'an County,Henan Province.The results show that this method can be used to perform inversion of paleo-landform of Ordovician limestone,infer occurrence space of ore-bearing rock series,and predict potential resource quantity of bauxite.With this method,the exploration depth is relatively great,thus meeting the requirement of deep bauxite detection.The resistivity contour lines of the section of CS... |
