摘　　要：广西贵港市龙头山矿区经勘探提交黄金工业储量,经过多年的开采,矿山保有资源量大为减少,已列为国家危机矿山,如何在矿区现有的地质资料基础上开展深部及外围找矿,扩大矿山可利用资源量、延长矿山服务年限已成为矿山首要课题。通过对龙头山矿区成矿地质条件、物化探资料进行综合分析,提出深部隐伏花岗斑岩体是寻找斑岩型铜、金矿体的直接目标,矿区南部、东部旺衣冲一带是铜矿有利成矿区。The Longtoushan Mining District in Guigang City,Guangxi Province,after exploration,has reported gold industrial reserves.After years of extraction,the remaining resource reserves in the mine have greatly decreased,leading to its classification as a national crisis mine.How to conduct deep and peripheral exploration for mineral resources based on the existing geological data in the mining area,expand the available resource quantity,and extend the mine's service life has become the primary focus.Through comprehensive analysis of the ore-forming geological conditions and geophysical and geochemical exploration data in the Longtoushan Mining District,it is proposed that the deep-seated concealed granite porphyry body is the direct target for finding porphyry-type copper and gold ore bodies,and the southern and eastern areas of the mining district,particularly Wangyichong,are favorable ore-forming areas for copper.
