摘要

    摘要
  • 摘要: 滇西北休瓦促钼钨矿床是义敦岛弧Cu-Mo成矿带南缘典型的热液石英脉型钼钨矿床，目前前人对该矿床主要开展了成岩-成矿年代学、岩石成因、动力学过程等研究。本文以白钨矿为研究对象，利用原位微量LA-ICP-MS以及原位Sr同位素LA-MC-ICP-MS测试技术对成矿流体演化及成矿物质来源开展了系统研究。白钨矿的产状和阴极发光图像显示其存在早中晚三个阶段，以中阶段白钨矿最为发育。早阶段白钨矿稀土配分与斑状二长花岗岩相似，呈轻稀土富集的右倾模式，Eu具有中等负异常（δEu=0.42），Mo平均含量为3.0%，87Sr/86Sr平均值为0.7098，与斑状二长花岗岩（0.7075~0.7098）接近；与早阶段相比，中阶段白钨矿轻稀土含量降低，Eu也具有中等负异常（δEu=0.37），Mo平均含量降低至2445μg/g，87Sr/86Sr值升高至0.7113；晚阶段白钨矿稀土配分呈中稀土相对富集的拱形模式，Eu基本无异常（δEu=0.93），Mo平均含量降低至56μg/g，87Sr/86Sr平均值为0.7083。从早到晚，白钨矿中轻稀土元素尤其是La和Ce的逐渐亏损表明存在氟碳铈镧矿的结晶；δEu升高和Mo急剧降低指示成矿流体从氧化到还原的转换；Sr同位素组成的变化指示了成矿物质来源的转变，早阶段岩浆流体贡献大，在中阶段白钨矿岩浆热液与围岩地层大规模作用下，地层为白钨矿的形成提供了大量Ca，表明强烈的水岩交互作用对矿床的形成发挥了重要作用。
    Abstract: BACKGROUND: The Xiuwacu Mo-W deposit is a typical hydrothermal quartz vein deposit in the Yidun island arc Cu-Mo metallogenic belt, northwest Yunnan. Numerous studies have been conducted on rock and ore chronology and petrogenesis, dynamics, but its ore-forming fluid evolution has been rarely studied.
    OBJECTIVES: To reveal the origin and evolution of ore-forming fluids of the Xiuwacu Mo-W deposit.
    METHODS: Scanning electron microscope (SEM) cathodoluminescence method, and in situ trace element (LA-ICP-MS) and in situ Sr (fs-LA-MC-ICP-MS) isotope analyses of scheelite.
    RESULTS: The occurrences of scheelite and the cathodoluminescence images indicated three generations of scheelite, Ⅰ, Ⅱ, and Ⅲ, with the middle stage scheelite being the most developed. The rare earth element pattern of the scheelite in the early stage was similar to that of the porphyritic granite. It showed a right-inclined pattern with light rare earth enrichment and a moderate negative Eu anomaly (δEu=0.42). The average Mo content was 3.0%, and the average 87Sr/86Sr was 0.7098, close to the specular feldspar granite (0.7075-0.7098). Compared with scheelite in the early stage, the content of light rare earth elements in the scheelite from the middle stage was low, and Eu also had a medium negative anomaly (δEu=0.37). Mo content was reduced to an average of 2445μg/g, and 87Sr/86Sr increased to 0.7113. The rare earth distribution pattern of scheelite in the later stage showed an arched pattern with relative enrichment of middle rare earth and no Eu anomaly (δEu=0.93). Mo content of scheelite decreased to 56μg/g, and average 87Sr/86Sr was 0.7083.
    CONCLUSIONS: From early to late, the gradual decrease of light rare-earth elements, especially La and Ce, in scheelite indicates the crystallization of bastnaesite. The increase in δEu and the sharp decrease in Mo content indicate the transformation of ore-forming fluids from oxidation to reduction. The change of Sr isotope composition indicates the change in the source of ore-forming materials. The magmatic fluid contributed a lot in the early stage, and the large-scale interaction between the magma-hydrothermal fluids and surrounding rocks is responsible for the formation of scheelite in the middle stage. The strata provide amounts of Ca for scheelite formation, indicating that strong water-rock interaction played an important role in the formation of the deposit.
