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。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.
