中文摘要:
      红牛—红山铜矿床位于西南三江成矿带义敦岛弧南段格咱压性弧,目前已达大型规模。本文以“成矿地质体+成矿构造及成矿结构面+成矿作用”成矿预测理论为指导,结合前人研究成果和近年来矿山地质工作,通过系统的野外地质调查,理清矿区关键控矿因素、矿化蚀变规律、找矿标志,建立了矿床成矿模式,即确定燕山期花岗岩为成矿地质体,岩性、褶皱和断裂构造组成了成矿结构面,在岩浆活动和交代作用后形成斑岩—矽卡岩—热液脉型铁铜多金属矿床,从岩体向外形成铜钼矿→铁铜矿→铜矿→铅锌矿→金银矿的矿化分布规律,依据找矿标志和该成矿模式,圈定了找矿预测靶区,为矿山下一步找矿工作提供直接依据。
英文摘要:
      The Hongniu-Hongshan copper deposit is located in the Geza pressure arc in the southern section of the Yidun Island arc in the Sanjiang metallogenic belt in Southwest China. It has reached a large scale at present. In this paper, guided by the theory of “metallogenic geological body+metallogenic structure and metallogenic structural plane+metallogenesis” mineralization prediction theory, combined with previous research results and recent mine geological work, through systematic field geological surveys, it has clarified the key ore-controlling factors, mineralization and alteration rules, and prospecting indicators, established the metallogenic model. That is, the Yanshanian granite is determined to be the metallogenic geological body. The lithology, folds and fault structures constitute the metallogenic structure surface. After magmatic activity and metasomatism, a porphyry-skarn-hydrothermal vein type iron-copper polymetallic deposit is formed. The mineralization distribution law of copper-molybdenum ore→iron-copper ore→copper ore→lead-zinc ore→gold-silver ore formed outward from the rock mass. Based on the prospecting signs and the metallogenic model, the prospecting prediction target area is delineated. Provide a direct basis for the next prospecting work.
