招远两涧地区金矿特征及成矿规律探讨

招远两涧地区位于玲珑金矿田的东北部边界,多数矿脉延至本区尖灭,本区金矿的特征为:矿脉众多,矿体规模为中小型,矿石类型以含金黄铁绢英岩化碎裂岩、含金黄铁石英脉为主,矿石品位较高。成矿规律为:矿体均受断裂构造控制;矿区南部矿体赋存在地表至-200 m标高之间共计600 m的范围内;36号脉、510号脉、209号脉为本区较大规模的矿脉,所含矿体在规模、数量、赋存位置等方面具有各自的规律。

Features and metallogenic regularities of gold mine in Liangjian region,Zhaoyuan

Liangjian region of Zhaoyuan is located on the northeast border of Linglong gold ifeld, and most veins extend to this region and then die out. The characteristics of gold mine in this region are summarized as follows： veins are numerous, ore body scale is medium and small, and the ore type is mostly gold-bearing beresitization cataclasite and gold-bearing pyrite quartz vein, the grade of ore is high. The metallogenetic regulation is summarized as follows：the ore bodies are all controlled by fault structures, and the ore bodies in the southern part of the mining area are held in the range of 600 meters from the ground to the elevation of-200 meters. Vein 36, Vein 510 and Vein 209 are the veins which have a large scale in the region, and the ore bodies have regulation respectively in scale, amount, and holding position.
