    青海双朋西—斜长支沟地区金矿成矿地质条件及成矿规律

    Ore-forming Conditions and Metallogeny of Gold Deposits in Shuangpengxi-Xiechangzhigou, Qinghai Province

    • 摘要: 双朋西—斜长支沟地区是青海东部较为重要的贵金属和有色金属成矿区.在已探明的金矿床中,有矽卡岩型、破碎蚀变岩型、石英脉型三类.金的成矿作用受构造-岩浆控制,在不同的岩性组合中分布着不同类型的金矿.矽卡岩型和石英脉型金矿赋存于二叠系中,破碎蚀变岩型金矿赋存于三叠系中.

       

      Abstract: The Shuangpengxi-Xiechangzhigou area is an important noble-nonferrous metalm ineralization zone in the eastern Qinghai province. Based on the proven gold deposits, there are three ore-forming types: skarn, a ltered cataclastic rock and quartz veins. Goldm ineralization is controlled by structure-magmatic events. Different gold deposit types exist in different rock association. The skarn-type and quartz veins gold deposits occur in the Permian strata, while the altered cataclastic breccias type gold depo sits are present in the Triassic strata.
