中文摘要:
      宁芜火山岩盆地中南段分布有较多的铜、金矿(床)点,其控矿因素一直备受争议,有人认为是受娘娘山古火山机构控制的,也有人认为是受NNE向与NW向两组基底断裂控制。本文通过开展矿产地质调查、剖析典型矿床,基于"三位一体"找矿预测法,研究认为宁芜火山岩盆地中南段铜、金矿成矿物质的聚集受石英二长岩(类)小岩株控制,在有利的构造空隙中以充填作用成矿,同时对深部可能出现的铜、金矿化类型进行预测,建立了区内铜(金)成矿模式,圈定找矿靶区3处。
英文摘要:
      In the central-south Ningwu volcanic basin occur many copper and gold deposits and occurrences and the ore-control factors are still controversial. It is considered to be controlled by Niangniangshan volcanic apparatus or by the basemental NNE or NW faults. Data of minerla resources survey and analysis of typical section show that accumulation of ore materials of the copper and gold deposits in the area is controlled by small stock of quartz monzonite and the material fills into favorite structural opening to be ore deposit. Possible copper and gold mineralization types to depth are predicted and the metallogenic model built and 3 tagets outlined.
