摘要: 通过收集内蒙古地区主要金矿床的最新资料,进行综合整理和分析,初步总结了内蒙古金矿床区域成矿规律,将全区划分为6个金矿成矿远景区;运用成矿系统理论,结合金多金属矿床成矿特征,在该区提出了9个金矿成矿系统;另外分析和总结其控矿因素及分布规律,认为内蒙古金矿床空间分布具有明显的区域性集中的特点,大部分金矿床分布于华北陆块北缘及华北板块北部大陆边缘金矿床成矿带中;矿床成矿时代为元古代、加里东期、华力西期和燕山期4个时期,主要集中在华力西期和燕山期成矿。根据金矿床成矿特点及其控矿因素,进一步提出找矿方向。

Abstract: The latest data of gold deposits in Inner Mongolia area is collected,collated and analyzed to primarily summarize the regional metallogenic regularity of gold deposits in Inner Mongolia.The research area is divided into six prospective areas of gold mineralization.According to the metallogenic characteristics of Au-polymetallic deposits,nine gold metallogenic systems are proposed in the area based on the metallogenic system theory.In addition,the ore-controlling factors and distribution regularities are analyzed and summarized.It is found that,the spatial distribution of gold deposits in Inner Mongolia have the obvious characteristics of regional concentration,and most of them are located in the metallogenic belt of gold deposits in the north margin of North China block and the northern continental margin of North China plate.The metallogenic epochs of gold deposits in Inner Mongolia are thought of 4 periods including Proterozoic era,Caledonian,Variscan and Yanshan,among which Variscan and Yanshan are the main metallogenic epochs.According to the metallogenic characteristics and ore controlling factors of gold deposit,the prospecting direction is further proposed.
