摘要
简要分析了区域成矿地质背景,地层构造及金矿床地质特征,重点论述了金矿分布规律。金矿分布在龙潭组底部;构造分级控矿明显;雄武背斜控制了Au,U,Sb,Fe,萤石矿分布;背斜轴部和两翼区域性断裂带控制了金矿化带、金矿床、矿点分布;小背斜、次级断层、层间破碎带控制金矿体分布和富集。金矿化与赤铁矿化、褐铁矿化、硅化、粘土化关系密切。金铀常相伴出现。区内有较好成矿远景。
Analyzing concisely the geological setting of regional mineralization, stratigraphic structure and geological characteristic, especially, the distribution laws of gold deposits are treated upon. The gold deposits, sited at the bottom of the Longtan Formation, are obvious under control of structural grading, in which Au, U, Sb, Fe and fluorite deposits are dominated by the Xiongwu anticline, and ore-body distribution and concentration are controlled by small anticline, second fault and informational fracture zone. Gold mineralization ties up with the hematitization, ferritization and silicification. Elements of gold and uranium occur together. A good prospecting is displayed in the area.
