| 中文摘要: |
| 矿区成矿元素地球化学以及成矿流体的初步研究表明,五台山七图金矿的成矿物质(金、银)主要来源于围岩的滹沱群四集庄组粗碎屑岩组合;变质基性火山岩的去硫作用提供了金矿化的硫源;韧-脆性剪切带的发育及活动是金矿化的动力学机制;成矿流体具有变质流体的性质,在变质基性火山岩中形成的蚀变岩与金矿化密切相关;矿床成因类型为沉积变质热液叠加型金矿床。 |
| 英文摘要: |
| The preliminary studies of geochemistry of ore-forming elements and ore-forming fluids indicate that ore-forming materials (Au,Ag) of Qitu gold ore deposit in Wutaishan area mainly originate from the coarse clastic rock association of Sijizhuang Formation of Hutuo Group; the desulfurization of metamorphic basic volcanics provided the sulfur source for gold mineralization; the existence and continuous development of ductile-brittle shear zone are the dynamic mechanism of gold mineralization; ore-forming fluid has the features of metamorphic fluid and is related to the alteration of metamorphic basic volcanics and gold mineralization; the genetic type for Qitu gold deposit is sedimentation-based ore deposit superimposed by metamorphic hydrothermal solution. |
