| 摘 要： | 北山地区与火山活动有关的铜多金属矿床主要有次火山斑岩型、火山喷溢型、火山沉积-变质型、沉积再造型和热液型,其中次火山斑岩型和火山沉积再造型是主要类型.通过对主要类型控矿条件的分析,得出与火山活动有关的斑岩型和海相沉积(改造)型多金属矿具有良好的找矿前景,并指出了具体的远景地区,认为本区不利于寻找海相火山岩块状硫化物型矿床.

| Abstract: | There are five metallogenic types of Cu-polymetallic deposits related to volcanic activity in the Beishan area such as sub-volcanic porphyry, volcanogenic sedimentation and reconstruction, volcanogenic sedimentation, volcanic effusion and metamorphism, and hydrothermal fluid types, while the two former are the most primary industrial types. Based on the analyses for the ore-orming conditions, it is concluded that the sub-volcanic porphyry and marine sedimentary polymetallic deposits related to volcanic activity have best prospecting potential, and several specific targets were indicated. It is disadvantage to find massive sulfide deposits associated with marine volcanic rocks in this area. |
