| 摘 要： | 甘肃成县庙沟—大沙湾铅锌矿区位于西秦岭多金属成矿带西段的西成铅锌矿田内,矿区的铅锌矿化受安家岔组条带状大理岩化灰岩和条带状大理岩的控制,喷流沉积(成岩)作用是成矿的主要因素,为喷流沉积的SEDEX型矿床,同生沉积特征明显,具热水沉积特征,发育有硫化物岩、重晶石岩、硅质岩等。预测靶区为马蹄沟一带近EW向岩相突变带。

| Abstract: | Miaogou-Dashawan lead-zinc property is located in Xicheng Pb-Zn ore field in west part of the west Qinling multi-metal ore belt. Mineralization is controlled by banded marbleized limestone and banded marble. Sedex is the main metallogenic factor. SEDEX feature is clear characterized by hot water sedimentation and development of sulfide rock, barite rock and siliceous rock. SEDEX type deposit may occur and it is predicted at abrupt facies change zone near Matigou. |
