中文摘要: 利用电子探针和等离子质谱(ICP-MS)分析手段,对下巴铅锌矿床中镉元素的分布特征进行分析研究,并探讨镉元素在矿床中的赋存方式。结果表明,该矿床铅锌矿化系列中的镉含量超过了其作为伴生有用组分的最低工业品位,矿床中镉元素主要赋存于闪锌矿中,与闪锌矿含量成正比关系。矿区范围内镉元素由南至北呈现出高—高—低的规律,在东西方向上,呈现出低—高—低规律。研究结果认为海底热液与热卤水共同参与了下巴铅锌矿成矿作用,矿床成因类型可归为海底热液和热卤水混合型。
Abstract:Based on the experimental results from the electron microprobe and inductively coupled plasma mass spectrometry (ICP-MS), analysis and research are made to investigate the distribution characteristics of Cd element in Pb-Zn deposit of Xiaba Mine, meanwhile its occurrence mode is also discussed. The results show that, the content of Cd element of the Pb-Zn mineralization series is higher than the minimum industrial grade as an accompanied valuable element. Cd element mainly occurs in the zinc blende, the content of which has a positive relationship with the content of zinc blende. Besides, Cd element has “high-high-low” and “low-high-low” regulations from south to north and from east to west in the entire deposit area, respectively. The minimization of zinc blende is a co-action of submarine hydrothermal solution and thermal brine, and its origin type should be a mix deposit of submarine hydrothermal solution and thermal brine.
