| 摘 要： | 湖北小经湾银矿位于秦岭－大别多金属成矿带中段南部。本文对该矿区岩石，构造及矿体的地球化学特征进行分析，探讨了成矿物质来源，热液来源及成矿机制，并建立了地球化学找矿标志。作者认为该矿受NW向断裂构造控制，并有向SE倾伏延伸之趋势。成矿物质既与围岩地层有关，又与中酸性岩浆岩（脉）有一定成生联系，属浅成低温混合热液型矿床，成矿时代为燕山晚期。

| Abstract: | The Xiaozhangwan silver deposit in Hubei Province lies in the south of the middle Qinling - Dabie multimetal minerogenetic belt. After analysis for rocks, structure and geochemical characteristics of the deposit, this paper discussed source of minerogenetic materials, hydrothermal origin and minerogenetic mechanism, and established geochemical ore - finding marks. The authors considered that this orebody is controlled by NW faults, with a dip of SE. Not only are minerogenetic materials connected to country rocks, but to acid - intermediate magmatic rocks(veins) in metallogeny also. It belongs to hypabyssal mixed hydrothermal- type deposit with low temperature, with mineralization epoch of Yanshanian period. |
