摘要：

This paper studied the deposit formation and metallogenic prediction of Hedong gold ore. Therefore, the first collected study area of geological material, including past research area regional tectonics, magmatic rocks the development conditions, etc; Then analyzes Hedong gold ore formation, structure, magmatic rocks and minerals composition, structure and structural, and expatiated wall-rock alteration and metallogenic physical and chemical conditions, the comprehensive on previous theory, this paper puts forward a explanation of the North China platform gold deposits distribution characteristics of gold metallogenic theoretical modes. The geological geochemistry of Hedong Gold ore indicate:Hedong Gold ore is a type of gold mine which is stringer-filling and surfer-lacking, potassic alteration takes priority in its country rock alteration, accompanied with sericitization and silicification. Different structure zones also formed. Ore-forming materials from Jiaodong group of granite-green rock zone strata, but the mineralization is likely crust-derived rich alkali fluid extensive metasomatism function analysis. Through to hedong gold deposits prospecting and metallogenic prediction research, summarizes the structure, lithology of ore-controlling rule, which could Provide the basis for the metallogenic prediction of Hedong Gold ore, and at the same time, it presents a new idea for the prospecting in the mine lot.
