辽宁北票北部金矿分布规律及找矿方向

北票位于华北地台北缘中段。区内出露较广的小塔子沟组片麻岩为主要赋矿地层。华力西、燕山期Au-Cu系列花岗岩广泛发育。主要产出承德—北票岩石圈断裂、鸡冠山和生金皋断裂。已发现的矿床(点)和矿化点严格受构造控制，由东北至西南呈近EW向展布，雁行状排列，可划出5条金矿化集中区段(矿田)。地层．构造．岩浆岩“三位一体”的地质背景为金矿成矿提供了有利的条件，而蚀变斜长角闪岩型(新类型)金矿体的发现又进一步拓展了找矿思路。在综合研究的基础上指出了不同类型金矿床找矿的有利地段。

The distribution rule and ore-finding direction of gold deposit in northern Beipiao, Liaoning

Beipiao is situated at the midsection of the northern margin of North China platform. The gneiss of Xiaotazigou Group is the major ore contain strata. The Au-Cu series granite of Variscan and Yanshan Period developed broadly. The Chengde to Beipiao lithospheric fracture, Jiguanshan fault and Shengjin'gao fault is the major structure of the area. The deposits (points) and mineralized points are all controlled by the structure strictly, they extended from Northeast to Southwest and arranged as echelon, and five gold mineralized concentration sections (ore field) are marked off. The geological background of strata-structure-magma provide well condition for gold mineralization, and the discovery of the altered amphibolite-type gold deposits also has extended the idea of ore-finding and pointed favored area for different types gold deposit based on the general study.
