摘　　要：玲南金矿床位于招平金矿带北段的破头青断裂带内,目前已探明矿床金属量近百吨,围绕该矿床台上矿段和坡头顶矿段开展了研究,为此提出玲南金矿床深部成矿预测浅析。主矿体最低控矿标高超过-1300m,矿体分枝、复合、尖灭、再现、膨缩特征明显。台上矿段Ⅰ-9号矿体具有较为明显的东北向侧伏规律,向深部未封闭,沿侧伏方向具有较大的找矿空间。研究表明,玲南金矿床主控矿断裂为破头青断裂,其广泛发育的裂隙对于含矿热液的渗透和扩散较为有利,且易于富集成矿。Lingnan gold deposit is located in the potouqing fault zone in the north section of Zhaoping gold belt.At present,the amount of gold metal in the deposit has been proved to be nearly 100 tons.The research has been carried out around the platform ore section and potoutou ore section of the deposit.Therefore,the deep metallogenic prediction analysis of Lingnan gold deposit is put forward.The lowest ore control elevation of the main ore body exceeds-1300m,and the ore body has obvious characteristics of branching,recombination,pinch out,reproduction and expansion and contraction.Ore body Ⅰ-9 in Taishang ore section has an obvious northeast lateral ambush law,is not closed to the deep,and has a large prospecting space along the lateral ambush direction.The study shows that the main ore controlling fault of Lingnan gold deposit is shatouqing fault,and its widely developed fractures are favorable for the infiltration and diffusion of ore bearing hydrothermal solution,and are easy to enrich and mineralize.
