| 摘 要： | 临武铁砂坪锡石—硫化物矿床位于香花岭多金属矿田内，属断裂充填交代型脉状锡矿床。矿区有锡石—硫化物和锡石—石英脉两种类型锡矿脉，严格受中泥盆统跳马涧组碎屑岩和棋子桥组灰岩中的NE、NW向断裂控制，Ⅳ号锡石—硫化物矿脉带长约2 500 m，宽500 m，平均品位Sn 0.36 %，最高品位Sn 1.36 %。矿脉产状与容矿断裂产状一致，赋存于棋子桥组的矿体为特殊的深浅相间的条纹岩，它是一种特殊的锡矿工业类型，在湘南地区具有找锡指导意义。

| Abstract: | Cassiterite - sulfide deposit of Tieshanping at Linwu, located in Xianghualing multi-metal mine, belongs to nervation tin-deposit of fracture-filled and replacement type. There were two types of tin veins, which were strictly controlled by northeast and northwest fractures of fragmental rock of Tiaomajian Group Devonian Series and limestone of Qiziqiao Group. Cassiterite - sulfide veins No.4 was about 2,500m long and 500m wide, with average grade Sn 0.36 %, and the highest grade Sn 1.36 %. The shape of mineral veins was the same as ore-bearing fractures. The ore body occurring in Qiziqiao Group was especial striped rock with interphase shade of color, and was an unusual industrial Sn-ore. It can direct exploring Sn deposit in south Hunan. |
