摘　　要：崇阳高枧钨、金多金属矿区位于长江中下游钨、金多金属成矿带,前人在此虽开展了大量矿产勘查和科研工作,但对该区深部成矿认识却无新进展,为探寻该地区深部找矿信息,笔者通过开展重磁异常特征、CSAMT异常剖面、广域电磁法剖面等工作,在高枧矿区南部发现的一处重磁低值正异常,并对2线,3线深部异常的电阻率中高阻隆起等现象进行研究,推断隐伏岩体分布于研究区西南部,其矽卡岩化接触带有利于W元素富集,是寻找矽卡岩型白钨矿的有利部位。推测高枧地区可能存在深部岩体,其位置应该在高枧西南部,区域空间位置显示岩脉最有可能来源于幕阜山岩体,两条北北东向断层形成了岩浆与矿液有利的运移通道。The Chongyang Gaoji tungsten and gold polymetallic mining area is located in the tungsten and gold polymetallic metallogenic belt in the middle and lower reaches of the Yangtze River.Although a lot of mineral exploration and scientific research work have been carried out in this area,no new progress has been made in the understanding of deep mineralization in this area.In order to explore the deep ore prospecting information in this area,the author has carried out work such as gravity and magnetic anomaly characteristics,CSAMT anomaly profile and wide-area electromagnetic profile.A positive gravity and magnetic low value anomaly was found in the south of Gaoview mining area,and the phenomenon of high resistance uplift in the resistivity of the deep anomaly of line 2 and line 3 was studied.It is inferred that the buried rock mass is distributed in the southwest of the study area,and its skarn contact zone is conducive to the enrichment of W element,which is a favorable location for searching skarn scheelite.It is speculated that there may be deep rock mass in Gaojian area,which should be located in the southwest of Gaojian.The regional spatial location shows that the dikes are most likely from Mufushan rock mass,and the two NE-trending faults form favorable migration channels for magma and mineral fluids.
