| 摘 要： | 英格庄金矿为胶东牟平-乳山成矿带上的一个中型金矿床。该矿床矿体严格受金牛山断裂带控制，呈脉状、透镜状和囊状平行斜列式产出；矿体平均厚1．58～1．98m，平均品位3．96×10^-6～4．77×10^-6。矿石类型主要为黄铁矿石英脉型；矿石中金属矿物主要为银金矿、自然金、黄铁矿等。围岩蚀变包括绢云母化、硅化、绿泥石化、黄铁矿化等。研究表明，英格庄金矿床为一中低温热液脉型金矿，属Groves等提出的造山型金矿范畴。

| Abstract: | Yinggezhuang gold deposit is a medium sized gold deposit which located in Muping - Rushan mineralization belt of Jiaodong peninsula. Its ore bodies are strictly controlled by Jinniushan fault, and occurred in veins, lens and cystic parallel oblique column type. The average thickness of ore bodies is 1.58 - 1.98m, while the average grade is 3.96 × 10 ^-6 -4.77 × 10^ -6. Its major ore type are pyrite quartz vein type. Metallic minerals are mostly composed of electrum, native gold, pyrite, and so on. Country rocks alteration includes sericitization, silicifica- tion, chloritization and pyritization, etc. It is showed that Yinggezhuang gold deposit is a medium - low temperature vein type gold deposit which belongs to Groves type orogenic gold deposits. |
