摘要
通过对香炉山钨矿床的构造及流体进行剖析,研究了其构造-流体-成矿系统三者之间的关系,旨在加深对其成矿的过程认识,并为今后矿山的研究及找矿工作提供思路。香炉山夕卡岩型白钨矿床受构造控制明显:隐伏岩体顶面接触带构造为最重要的控矿构造,褶皱控岩,为成矿物质的来源提供保障,裂隙及层间破碎带不仅为成矿物质的运移提供运移通道,也是较重要的储矿场所,但后期发育的裂隙具破矿性;流体与该矿床的形成息息相关,其中的石英-白钨矿阶段及石英-硫化物-白钨矿阶段为矿床的主要成矿期;香炉山夕卡岩型白钨矿床的构造-流体-成矿三者之间具有高度的协调性及关联性,对形成香炉山大型白钨矿床极为有利。
For the purpose of deepening the understanding of the ore-forming process,and offered the thinking for prospecting work in the future,this paper analyzed the structure and fluid of the Xianglushan tungsten deposit,and the relationship of structure-fluid-ore forming.The Xianglushan tungsten deposit is obviously controlled by the structure,fold,fracture（fault and cleavage）,contact zone structure,interlayer fracture zone and wall-rock lithology,which affect the formation of the ore-body.Fluid is also closely related to the formation of the deposit with the phase of the quartz-scheelite and quartz-sulfide-scheelite occuring during metallization period.The structure-fluid-ore forming systems have a high degree of coordination and connection,which is the key to form large scheelite deposit in the Xianglushan.
