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.
