本文亮点

柏杖子金矿是我国冀东—辽西金成矿带上典型的岩浆热液型金矿，经过多年持续开采，该矿山保有资源量逐渐减少，因此，系统地开展矿区控矿规律研究工作，对于合理布置探矿工程以及增加矿山资源储量具有重要意义。通过总结柏杖子金矿成矿地质条件，结合野外地质调查，认为矿区金矿体主要受柏杖子岩体和构造系统的联合控制。其中，岩体内部的原生节理—叠加断裂和岩体外部的断裂共同控制着脉状矿体，NE向含矿构造组与NEE向含矿构造组交会部位金矿化较发育，易形成蚀变岩型厚大矿体。通过综合研究，建立了矿区成矿模式，认为柏杖子金矿的成矿地质体为深部隐伏岩体，推测该矿区深部可能存在斑岩型矿体。矿区西南部苗金沟浅部新发现了石英细脉型矿体，推测深部存在类似柏杖子岩体内的石英脉型矿体和蚀变岩型（细脉浸染型）矿体。

Highlights

Baizhangzi gold deposit is a typical magmatic hydrothermal deposit in the gold metallogenic belt of eastern Hebei and western Liaoning in China，and the orebody occurs in granite.After years of continuous mining，the amount of retained resources in the mine has gradually decreased.Therefore， it is of great significance to systematically carry out the research on the ore-controlling law in the mining area for the rational arrangement of prospecting projects and the increase of mine resource reserves.By summarizing the metallogenic geological conditions of Baizhangzi gold deposit and combining with the field geological survey，it is considered that the gold orebody in the mining area is mainly controlled by the combination of Baizhangzi rock mass and structural system.Among them，the primary joint-superimposed fracture inside the rock mass and the fracture outside the rock mass jointly control the vein orebody.The gold mineralization at the intersection of NE-trending and NEE-trending ore-bearing structure group is more developed，and it is easy to form altered rock type thick orebodies.Through comprehensive research，the metallogenic model of the mining area is established.It is considered that the metallogenic geological body of the Baizhangzi gold deposit is deep concealed rock mass，it is speculated that there may be porphyry orebodies in the depth of the mining area. The new quartz vein type orebody was found in the shallow part of Miaojingou in the southwest of the mining area，it suggests that there are quartz vein type and alter rock type orebodies similar to the those in the Baizhangzi rock mass in the depth.
