| 摘 要： | 农戈山铅锌矿地处鲜水河断裂带内的折多山酸性侵入岩基,空间分布上受北西向鲜水河断裂带及北北西向磨西河断裂带制约.发育的三条矿脉受构造控制,赋存于喜山期折多山碱长花岗岩体的含矿碎裂花岗岩中；在构造运动的作用下,岩体形成碎裂岩,含矿热液在裂隙中充填、交代、沉淀,从而呈浸染状、网脉状矿石形成工业矿体,认为该矿床为受断裂构造控制的中低温热液充填型或细脉浸染型Cu、Pb、Zn、Ag多金属矿床,具多期成矿特征,并归纳了主要找矿标志.

| Abstract: | Nonggeshan lead-zinc deposit is located in Zheduoshan acid intrusive rock foundation within fault zone of Xianshui river, and restricted by fault zone of NW Xianshui river and NNW Moxi river in space distribution.Three developmental veins is controlled by structure,and hosted in cataclastic ore-bearing granite of Zheduoshan alkali feldspar rock mass in Himalayan period. Under the action of tectonic movement,the rock mass formed cataclastic rock,the ore-bearing hydrothermal solution filled,precipitated and s... |
