| 中文摘要:文章总结了前人对百灵山铁矿的研究成果，并对已发表的地质图件进行了修正。首次对矿石中含矿石英脉中的流体包裹体进行了Rb-Sr等时线年龄测定，结果为（293±10） Ma，确定了该矿床的成矿时代为石炭纪末—二叠纪初。 |

| Abstract:The Bailingshan iron deposit, located in the south of the Later Paleozoic Jueluotage island arc belt, is hosted in thickly_stratified volcanic clastic rocks of the middle Carboniferous Matoutan Formation, which is the type of SEDEX_hydrothermal reformation. In this paper, the authors use the Rb_Sr isochron dating method first time to measure the forming time of quartz fluid inclusion from iron_bearing quartz veins, and the result yields (293±10) Ma. Therefore, the ore_forming time of the Bailingshan iron deposit is suggested to be from later Carboniferous to early Permian. |
