摘要: 四川拉拉地区是我国西南重要的铜矿产地,研究该地区铜矿的成矿规律和找矿潜力,对于进一步的地质找矿工作具有重要意义。拉拉地区的铜矿均为与河口群火山喷发作用有关的铁氧化铜金矿床,矿床产于古元古河口群钠质火山岩系中,具有成群、成带和多层分布的特点,并伴生铁、钼、钴、金、硫等多种组分可综合利用。控矿因素和找矿标志研究表明,矿区F1断层南北两个远景区均有找矿潜力。JPAbstract: The Lala district is the important copper producer in southwest China, and it is vital to study the metallogeny and potential in copper deposits of this district. These copper deposits are iron oxide copper deposits, which related to volcanic eruption of the Hekou Group. These deposits are hosted in sodic volcanic rock series and distributed in multi-layers as clustering and banding. These deposits contain economic amount of Au-Mo-Co-REE-Fe. The ore-control factors and ore-hunting indicators results show that the South and North prospect areas of F1 fault have potential of ore deposits.
