朱溪式矽卡岩型矿床成矿作用及找矿方向
|
摘要
朱溪钨铜多金属矿床是近年在赣东北地区新发现的与岩浆活动有关的超大型矽卡岩型矿床。在已有研究成果的基础上,结合最新勘探成果,论述了该矿床基本地质特征,并通过将该矿床与传统意义上矽卡岩型矿床对比,从蚀变分带、成矿温度、成矿阶段、钨铜共生机制、控矿因素等对其独特性特征进行了初步探讨,并简要论述了朱溪矿床成矿作用过程,建立了朱溪式矽卡岩型钨铜多金属矿床成矿模式,指出了今后区域上应重视推覆构造带内中酸性岩浆侵位于碳酸盐岩地段的找矿,朱溪矿区应重视北西侧及深部矽卡岩型和蚀变花岗岩型钨铜多金属矿、北东侧脉型铜锌银矿的找寻。
The Zhuxi W-Cu polymetallic deposit,newly discovered in northern Jiangxi in recent years,is a super large-scale skarn deposit related to magmatic activities.Based on the previous studies and the latest exploration achievements,this paper discusses the basic geological characteristics of the Zhuxi deposit.By comparison with typical skarn deposit,the paper also studies preliminarily the unique characteristics from alteration zoning,mineralization temperature,mineralization stage,W-Cu symbiosis mechanism and ore controlling factors.The paper then briefly discribes the mineralization process,the establishement of the"Zhuxi type"skarn W-Cu polymetallic deposit metallogenic model,and points out the regional prospecting direction should be pay attention to favorable area which intermediate acid magma invades the carbonate rocks.In the Zhuxi area,we should focus on finding skarn and altered-granite type W-Cu polymetallic deposit in the NW side and deep,hydrothermal vein type Cu-Zn-Ag deposit in the NE side.
