湘中包金山金矿床地质特征及找矿预测

Geological Characteristics and Prospecting Prediction of Baojinshan Gold Deposit in Central Hunan

包金山金矿位于湘中成矿区的北东部,属湘中地区典型金矿床。地层主要为新元古界板溪群马底驿组,主构造为向北倾的单斜构造,其中近东西向断裂的主要控矿构造控制了矿床的空间定位,层间破碎带和北西向断层则作为重要的赋矿构造。文章结合土壤地球化学特征,分析总结包金山矿床地质特征,并对包金山矿区圈定3个找矿前景区。

Baojinshan gold deposit is located in the eastern part of central Hunan metallogenic area,it is a typical gold deposit in central Hunan.The stratum is mainly Madiyi Formation of the Neoproterozoic Banxi Group that the main structure is a northward-dipping monoclinal structure.The main ore-controlling structure of the near east-west fault controls the spatial location of the deposit.The interbedded fracture zone and the NW fault are important ore-bearing structures.Soil geochemical characteristics have been combined in this study,the geological characteristics of Baojinshan deposit are analyzed and summarized,and three prospecting prospect areas are delineated in Baojinshan mining area.
