鄂东南章山铜铅锌多金属矿床成矿地质条件与成矿规律分析

The ore-forming geological condition and metallogenic regularity of Zhangshan Cu-Pb-Zn polymetallic deposit in Southeast Hubei

根据近年来的地质勘查资料,通过对鄂东南章山铜多金属矿床成矿地质条件与成矿规律进行综合分析,发现其成矿元素、围岩蚀变具有分带特征,符合深源流体成矿模式。认为铜铅锌多金属矿(化)体主要赋存在奥陶系与EW向断裂破碎带复合部位,受地层、断裂破碎带控制;区内成矿地质条件有利,控岩、控矿规律明显,本区具备寻找大型沉积-热液改造型矿床的远景和潜力。

Based on the data of geological exploration in recent years,the metallogenic and geological condition and ore-forming regularity of Zhangshan copper-polymetallic deposit in the southeast of Hubei Province are comprehensively analyzed.It is found that the metallogenic elements and wall rock alteration types have zonal characteristics,being coincident with the metallogenic model of deep source fluid.It is considered that the ore bodies are mainly hosted in the composite part of Ordovician system and EW fault zone,which are controlled by the strata and fault zone.The ore-forming geological condition is favorable,and the rock-controlling and ore-controlling regularities are obvious.There is the prospect and potential to explore for the large-scale sedimentary hydrothermal reformed-type deposit in this area.
