摘　　要：宝兴厂矿区是一个与喜马拉雅期富碱斑岩有关的多金属成矿集中区,具有斑岩型矿床特征,岩体与围岩接触带、近东西向构造裂隙带是主要控矿构造,奥陶系地层与斑岩体具有明显的物性差异,利用EH4连续电导率物探测量能够较好地反映出隐伏的斑岩体与围岩接触带部位,对该区深部地质找矿具有指导作用。Baoxingchang deposit, which has relationship with Himalaya period Fe - rich porphyry, is concentrated area of polymetallic mineralization ; with character of porphyry type deposit ; the main ore controlled structure is contact zone of porphyry unit and wall rock, near EW direction tectonic fracture zone ; Ordovician system stratum has obvious physical-property contrast with porphyry unit; using EHg continuous conductivity measure can reflect insidious contact zone of porphyry unit and wall rock better, which has guidance meaning of deep geologic EXPLORATION in this area.
