新寨锡多金属矿的找矿方法与潜力

新寨锡矿是近年来发现的大型锡矿床,在前期区域地质调查和化探工作基础上布置了综合物探方法.按照矿区外围就矿找矿的思路,应用电磁测深和双频激电法对工作区进行勘探,结果表明新寨工作区深部具有良好的成矿前景.电磁测深能够反映地下岩层展布形态和相关电性异常,激电测量能反映出该区幅频率异常范围及良好的矿体极化特征;再结合多种资料,...

ORE-PROSPECTING METHODS AND POTENTIAL ANALYSIS OF THE XINZHAI TIN-POLYMETALLIC DEPOSIT

The Xinzhai ore deposit discovered in recent years is a large-size tin deposit. On the basis of early period regional geological and geochemical survey, an arrangement of integrated geophysical methods was made. In accordance with the idea of outskirt ore-prospecting and ore-search based on known ore spots, the dual-frequency electromagnetic sounding IP method was employed in the work area. Electromagnetic sounding underground rock reflected the fabric patterns and related electrical anomalies, while IP measurements reflected the limits and unusual polarization characteristic frequency of a good ore body. In combination with various kinds of information and professional knowledge, the analytical capacity of geological ore-prospecting can be improved and the risk can be reduced. It is shown that at the depth of the Xinzhai work area there exist good prospects for mineralization.
