| 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 metal mineralization zone in the eastern Qinghai province.Based on the proven gold deposits,there are three ore-forming types: skarn, altered cataclastic rock and quartz veins.Gold mineralization 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 deposits are present in the Triassic strata. |
