摘要
为提高物探方法在整装勘查区攻深找盲工作中的有效性,开展大比例尺综合物探技术等关键基础地质研究工作。在典型矿床开展激电中梯、激电测深等常规直流电法,以及可控源音频大地电磁测深、瞬变电磁等工作方法,采用合理的数据处理方法,提高矿致异常的刻画精准度,总结不同物探方法在整装勘查区适用性和有效性。通过该项工作,在栾川地区铅锌金银矿整装勘查区内取得了较好的矿产勘查指导效果,对其他地区铅锌金银矿勘查工作也具有借鉴意义。
In order to improve the effectiveness of geophysical prospecting technology for exploring deep and concealed orebodies,it carried out large scale geophysical exploration of key basic geological research in integrated exploration area.It conducted IP intermediate gradient,IP sounding,CSAMT and TEM,and then it can increase SNR and increase accuracy of mineralized anomaly by logical data processing method,and discuss the applicability and effectiveness of methods combination.It achieved results in Luanchuan lead zinc ore deposit integrated exploration area,which has a certain significance to similar lead,gold and silver ore deposits.
