胶东金矿研究进展及约束金物质来源的新思路

Research Advances of Metallogenesis of Gold Deposits in Jiaodong Area and a New Idea for the Research of Ore forming Material Sources

摘要:

作为全球最主要的金成矿带之一，胶东地区仅占全国国土面积的0.27%，黄金储量却约占全国的25%，特别是胶西北地区的金矿更是星罗棋布，引起了国内外地质学家的广泛关注，进行了大量的生产和科研工作。该文总结了近年来取得的关于胶东金矿在构造、岩浆、流体及成矿物质、富集机制等方面取得的研究进展，并且针对颇具争议的金成矿物质来源问题，提出了新的研究思路，并初步论证了其可行性。以期抛砖引玉，引起广大地学同仁对此科学问题的关注。

Abstract:

As the world's most important gold metallogenic belt, the square of Jiaodong area accounts for only 0.27% of the territory in China, but gold reserves account for about 25% of the country, especially in northwest of Jiaodong area, gold deposits spread widely. Jiaodong gold mineralization area（JGA for short）has received tremendous international attention in the research of gold mineralization. Previous researches have gotten quite a few study achievements on JGA. In this paper, great achievements gained in geological setting, regional structures, magmatism, metallogenetic fluid and metallogenic mechanism of the JGA in recent years have been summarized. The oreforming material sources is often ambiguous and raises wide concerns. It is still a bottle neck limiting the development of the further research due to the lack of direct petrological or mineralogical vidence. For this reason, a new research idea has been presented on the basis of the predecessors studies. It is hoped to be able to provide some references for the research in this area.
