| 摘 要： | 矿区成矿元素地球化学以及成矿流休的初步研究表明，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－脆性剪切事宾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。 |

| Abstract: | 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. |
| Keywords: | Qitu gold deposit characteristics for ore forming materials genesis of ore deposit metaconglomerate type gold deposit ore forming fluid ductile shear zone Wutaishan area |
