摘　　要：　高龙金矿为产于滇黔桂裂谷中的热水沉积型矿床。中、下三叠统为有利的赋矿层位;右江裂谷带及晚古生代坳陷区中的小隆起为成矿提供了有利的构造环境,生长断裂及其旁侧长兴组中的局部洼陷是有利的控矿构造及矿化富集部位;硅化与金矿化关系密切,矿化富集与黄铁矿、褐铁矿、水云母、毒砂、辉锑矿等矿物及其相应的蚀变关系密切。根据成矿地质特征及成矿作用的研究,建立了成矿模式。Gaolong Au deposit is a sedex deposit in Dian-Qian-Gui rift. Middle and lower Permian strata are the favorable wall rock. Small lift in Youjiang rift zone and Late Palaeozoic sag is the favorable structural environment. Au-concentration are controled by the growth faults and local depression in Changxing formation on the either side of the faults. The mineralization is closely related to silicification and the concentration to pyrite, limonite, hydro-mica, arsenopyyite, stibnite and the corresponding alteration assembly. The ore-forming model is set up based on the study of geological characteristics and ore-forming processes.
