| 摘 要： | 玲珑金矿田东风矿床171号脉金矿，产于胶西北地区著名的玲珑金矿田南东部，受NEE向破头青断裂控制。矿脉、矿体形态、产状与断裂带基本相同，带内岩石蚀变分带现象较明显；矿体主要分布于断裂带下盘，呈似层状、大脉状，沿走向及倾向显舒缓波状，局部具分支、复合特征；厚度变化较稳定，有用组分分布较均匀；矿石类型包括黄铁绢英岩型和黄铁绢英岩质碎裂岩型。研究表明，中生代燕山晚期的构造—岩浆活动为成矿提供了热源及定位空间，成矿物质具壳、幔混合源特征，成矿流体主要来源于幔源，有大气水和岩浆水的加入；矿床成因为中温热液型金矿。

| Abstract: | No.171 ore vein in Dongfeng deposit in Linglong gold field is located in southeast part of the famous Linglong gold mine in northwestern Jiaodong, and controlled by Potouqing fault belt with the trend of NNE. The ore vein, ore body shape, occurrence and the fault belt are basically the same. The alteration zoning of the rocks is evident. The ore bodies are mainly distributed in the footwall of the fault belt, and showed as bedded and big vein form. It showed as little undulatory forms along the trend and had compound characteristics in partial area. The change of thickness of ore bodies is stable. The useful components distributed uniformly. The ore types include pyritized phyllite and pyritized phyllite cataclastic rocks. As showed by the research, magmatic activities in late Yanshan period of Mesozoic provided the heat source and space location for mineralization. The ore-forming metals have the characteristics of mixed types of crust-mantle. The ore-forming fluids mainly came from the mantle and mixed with meteoric water and magma water. It is a middle temperature hydrothermal gold deposit. |
