| 摘 要： | 金青顶金矿是我国最大的石英单脉型金矿.控矿断裂呈NNE向,具多期活动特点,矿体赋存于断裂呈张性的转折部位;主矿体呈脉状,矿体向NE侧伏,侧伏延深1 080 m,是矿体最大走向长度的2.7倍;矿床有4个富矿柱,赋存于控矿断裂拐弯最大、受张应力作用最强部位,也是多阶段成矿作用叠加部位;矿床为中温热液充填型金矿.在成矿过程中,胶东群是成矿物质的主要来源,岩浆活动是热源并提供成矿热液,构造活动是成矿的动力并提供容矿空间,构成"三位一体"成矿模式.

| Abstract: | Jinqingding gold deposit is the biggest single ore vein type deposit in China.It is controlled by NNE fault active in multiple stages.Ore bodies are located at dilatance where the fault turns direction.The main ore vein pitches about 1080m(about 2.7 times of extension along its strike) in NE direction.In the deposit there are 4 bonanza where is the most dilatant turning point of fault thus the tensile stress is strongest and multiple ore-forming processes were overprinted.Genetically it is a hydrothermal fluid filling gold deposit.In the ore-forming processes Jiaodong group provide it with ore materials,the magmatism with heat source for ore fluid,tectonism with dynamics and location space that is the three in one ore-forming model. |
