| 中文摘要: |
| 九子沟铜矿位于铅硐山—铜牌沟铜铅锌成矿带中部。矿区赋矿部位为星红铺地层内灰岩与千枚岩接触面及其附近,此界面两侧岩性能干性相差大。一方面在北东向应力作用下,在二者接触部位容易形成滑脱,为成矿热液向上运移提供通道。另一方面,二者构成“硅钙面”,引发流体物理化学条件变化,导致矿质沉淀。矿床矿体主要呈层状、似层状,局部为透镜状。根据矿区成矿地质环境、矿体特征、成矿物质组分、矿石组构、成矿物质来源等特征,初步确定了九子沟铜矿床的成矿要素及成矿模式。 |
| 英文摘要: |
| Jiuzigou copper deposit is located in the middle of Pb-Zn-Au metallogenic zone of Qiandongshan-tongpaigou district. The glebe in this mining area is the contact zone and its vicinity of limestone and phyllite in Xinghongpu group. The competence of rocks on both sides of the boundary are very different. On the one hand, under the action of northwest stree, it is to easy to form a decollement to provide a channel for the ore-forming hydrothermal to travel. On the other hand, the contactformed a “silicium-calium contact” which caused the change of the physical and chemical conditionsand mineral material precipitate. The ore bodies are layered and lentiform, locally as vein. According to the metallogenic geological environment, characteristics of orebodies, ore-forming material, ores’ structure and material source,this paper preliminarily determine metallogenic factors and metallogenic model of the Jiuzigou copper deposit. |
