摘要
玉龙铜(钼)矿区是受岩浆热液作用和气液交代作用形成的典型斑岩—矽卡岩复合型矿床。在收集和阅读前人研究成果和技术资料的基础上,结合工作实践,通过对矿床的基本地质特征、成矿背景、矿化类型、围岩蚀变以及控矿条件和成矿作用等因素进行探讨,得出了该矿床的大体成矿过程,解释了玉龙铜(钼)矿区Ⅰ、Ⅱ、Ⅴ号矿体不同的成因背景和特征,并在此基础上建立了早期以斑岩—热液体系为核心,晚期以中低温热液—地下水对流循环为主的复合型成矿模式,为西藏三江地区同类矿床的寻找和勘查提供依据和指导。
Yulong Cu (Mo) Deposit is a typical porphry-skarn composite deposit, which is formed in the mag- matie hydrothermal and gas-liquid metasomatism. Based on systematic collection and review of previous studies of Yulong Deposit, combined with the working practice, and through the deposit basic geological characteristics, met- allogenic backgrounds,mineralization types, wall-rock alterations, ore-controlling conditions and mineralization fac- tors,the general ore-forming process and model were studied in this paper. At the same time, the different forming backgrounds and featuresof the I , II , V Ore-bodies of Yulong Cu(Mo) Deposit were explained. And based on the former studies, the porphyry-hydrothermal system was established as the core of mineralization model during the early stage, the convective circulation of low to moderate temperature hydrothermal-groundwater as the main com- posite mineralization model in late stage. Meanwhile, it provided theoretical foundation and indicative function for the same type of deposits finding and exploration in Sanjiang Area in Tibet.
