赣北朱溪与大湖塘钨多金属矿床对比研究
|
摘要
近些年在赣北朱溪和大湖塘地区新发现了世界级钨多金属矿,引起了广泛关注。文章对朱溪和大湖塘钨多金属矿床成矿地质特征进行综合对比研究,发现2个矿区成矿岩体和矿源层较为相似,而导矿-控矿构造、矿体类型、围岩蚀变等方面则存在差异性;从岩体、构造、围岩蚀变、地层等方面总结了找矿标志,并建立了赣北地区"多位一体"钨矿找矿预测模型,简要提出下一步的找矿方向。
In recent years, world-class tungsten polymetallic deposits have been discovered in the Zhuxi and Dahutang regions of northern Jiangxi Province, which has attracted extensive attention. In this paper, the metallogenic geological characteristics of Zhuxi and Dahutang tungsten polymetallic deposits are studied comprehensively. The results indicate that the metallogenic rock masses and source bed are relatively similar in the two mining areas, while there are differences in ore conduit and ore control structure, ore body characteristics, wall rock alteration. The prospecting criteria are summarized from the aspects of rock mass, structure, wall rock alteration and stratum, and a prospecting prediction model for tungsten deposits with multiple geological characteristics is proposed, which can provide reference for the further prospecting direction.
