中文摘要:
      内蒙古宁城地区出露加里东海西期煌斑岩脉群,其中云斜煌斑岩内,沿燕山期韧性剪切片理化带,分布金矿体。煌斑岩是宏观找金的标志。金矿体中硅化、绿泥石化、方解石化发育。主要金属矿物是黄铁矿。金主要以显微和次显微自然金包裹体,赋存于黄铁矿内。微量元素V、Ni浓度高。与金相关的元素为Bi、Mo,金矿成因类型为幔源C-H-O流体分异演化热液型金矿。
英文摘要:
      In Ningcheng Area, Inner Mongolia Au ore bodies Occur along schistozed rock zone of the Yanshenian ductile shaar zone within lamprophyres, which are Au ore prospecting target macro scopicaly. The ore bodies are developed with silicification, chloritization and calcitization. Pyrite is the major ore mineral. Micro and sub-micro native gold inclusion is the dominant occurrence in pyrite. Micro-elements of V and Ni are in higher concentration and Bi, Mo are correlated to Au.The Au deposit is of mentle-sourced C-H-O differentiational and evolutional hydrothermal fluidGold deposit.
