摘要
Abstract
The studied gold deposit in Tanzania is a concealed ore deposit associated with BIF. In order to find out the distribution of the gold ore veins,the authors conducted ground high precision magnetic survey. The results show that the △T anomalies are mainly negative anomalies,whose peak value is higher than that of positive anomalies,which seem to be associated anomalies. The anomalies basically reflect the extension of BIF in plane and characteristics of the structure. The induced polarization depth measurement along the section shows that the contour lines of apparent resistivity are concave whereas the contour lines of apparent polarizability are convex,respectively reflecting the position of structure along the section and the features of BIF. The magnetic force and induced polarization anomaly in this area display obviously the concealed feature of BIF,and the bed of interest is intersected by drilling. The results are valuable in the deployment of drill holes.关键词
