研究了中国火山次火山岩—斑岩金银矿成矿系列的划分、成矿构造环境、矿床类型、成矿形式。该系列金银矿划分为 6个亚系列 :大陆边缘与高钾钙碱性英安—流纹岩有关的Ag—Au成矿亚系列 ;古生代岛弧区与富钠高碱玄武岩拉斑玄武岩有关的Au(Cu、Ni、Cr)成矿亚系列 ;陆内裂谷、裂陷区富碱高钠中基—中酸性火山岩有关的Au—Cu—Fe成矿亚系列 ;地槽褶皱带钙碱性安山—流纹质火山岩有关的Ag—Sn—Cu—Pb—Zn— (Au)成矿亚系列 ;中新生代岛弧一板块碰撞带碱性—亚碱性长英质斑岩型Au—Cu—Mo—Pb—Zn成矿亚系列 ;台缘高甲安山—流纹质火山岩有关的Au—Ag(Cu)成矿亚系列。将成矿系列划分出 7个成矿形式。
The division of volcanic sub-volcanic-porphyry gold-silver mineralization series, metallogenic tectonic setting, ore deposit type and metallogenic model have been studied. This series of gold and silver deposits is divided into six sub-series: the Ag-Au mineralization sub-series related to the high-K calc-alkaline amphibolite in the continental margin; the Paleozoic island arc zone related to Na-rich high-alkali basaltic rock basalts Au (Cu, Ni, Cr) mineralization sub-series; Au-Cu-Fe metallogenic series related to alkali-rich, high-sodium and medium-acidic volcanic rocks in inland rift and rift zone; Ag-Sn-Cu-Pb-Zn- (Au) metallogenic sub-series related to the Archean-rhyolite volcanic rocks; the Mesozoic-Cenozoic arc-plate metamorphic belt with alkaline- Cu-Mo-Pb-Zn metallogenic sub-series; Au-Ag (Cu) metallogenic series related to the Gaojia’an-rhyolitic volcanic rocks in the margin. The metallogenic series is divided into 7 metallogenic forms.
