常规电、磁法在安徽箬岭金矿勘查中的应用

Application of conventional electric and magnetic methods in the exploration of Ruoling gold deposit in Anhui

为配合地质工作,在安徽箬岭金矿区先行安排了激电中梯剖面测量、测深和磁测工作,圈定了2条磁异常带、5条视电阻率低阻带及1条高极化率异常带,根据磁异常和视电阻率低阻异常解译了5条北东向构造和1条北西向断裂构造,其中F1、F4断裂走向北东,产状近直立略为南倾,为较好的含矿构造。文章着重从矿区电、磁法扫面和测深剖面异常3个方面来阐述物探异常在该矿床勘查过程中的指导意义。

The intermediate gradient IP profile measurement,IP sounding section and magnetic work were conducted in the Ruoling gold deposit area,Anhui Province to support the geological exploration work. Totally two magnetic anomalous zones,five low apparent resistivity zones and one high polarizability zone were outlined. Based on the magnetic anomaly and low apparent resistivity anomaly,5 NE- trending structures and 1 NW- trending fault structure were interpreted,where F1 and F4 fault strike NE with steep angle and dip to the south slightly,which are main ore- bearing structures. This paper discussed the importance of geophysical anomalies in the exploration of the Ruoling gold deposit from three aspects,i. e.,electrical method,magnetic anomaly and IP sounding section method.
