| 摘 要： | 鄂东南地区灵乡岩体东缘铁矿主要为矽卡岩型铁矿,受岩体与其内部的大理岩捕虏体接触带控制,特别是断裂接触复合带,往往是成矿的有利部位;金矿主要为热液型金矿,受断裂破碎带控制,金与金属硫化物密切相关,成矿物质来源于深部小岩体。在现阶段找矿工作成果的基础上,总结和分析灵乡岩体东缘铁、金矿的成矿地质特征、控矿因素,总结找矿标准,建立找矿模型,进而对本区铁矿、金矿的找矿方向进行探讨。

| Abstract: | The iron deposits in the eastern margin of Lingxiang pluton in Southeastern Hubei are mainly skarn type,which are controlled by the contact zone of marble xenoliths in the rock mass and its interior,especially the fault contact complex zone,which is often a favorable position for mineralization;The gold ore is mainly hydrothermal type gold deposit,controlled by the fault fracture zone,which is closely related to the metal sulfide,and the oreforming material comes from the deep small rock body.On the basis of the results of current prospecting work,this paper summarizes and analyzes the ore-forming geological characteristics and ore controlling factors of iron and gold deposits in the eastern margin of Lingxiang rock body,summarizes the prospecting standards,establishes the prospecting model,and then discusses the prospecting direction of iron and gold deposits in this area. |
