斑岩型铜矿勘查中综合物探法的应用研究

Application of Comprehensive Geophysical Exploration Method in Exploration of Porphyry Copper Deposits

在金属矿的不断开发中,地表易识别的矿物逐渐减少,需要加强各类勘查技术的应用,提高找矿效率及精度。单一物探法在勘查中存在一定的不足。以A矿区的勘探为例,研究综合物探法的应用。基于对矿区地质特征的了解,选择重力法、磁法、电法等物探方法进行综合应用,然后进行实际勘查及数据分析。最后,在对物探异常找矿效果进行探讨后,又进行了多参数综合分析、互相补充及互相验证。证实综合物探法能降低物探勘查的多解性,提高地质解释的可信度,实现对斑岩型铜矿的有效勘查。

In the continuous development of metal mines,the easily recognizable minerals on the surface are gradually decreasing,and it is necessary to strengthen the application of various exploration technologies to improve the efficiency and accuracy of mineral exploration.The single geophysical method has certain shortcomings in exploration.Taking the exploration of mining area A as an example,the application of comprehensive geophysical exploration method was studied.Based on the understanding of the geological characteristics of the mining area,geophysical methods such as gravity,magnetic,and electrical methods were selected for comprehensive application,followed by actual exploration and data analysis.Finally,after exploring the effectiveness of geophysical anomaly exploration,a comprehensive analysis of multiple parameters,mutual supplementation,and mutual verification were carried out.Confirming that the comprehensive geophysical method can reduce the ambiguity of geophysical exploration,improve the credibility of geological interpretation,and achieve effective exploration of porphyry copper deposits.
