康滇地轴东缘典型铅锌矿床伴生分散元素镉锗镓赋存状态与富集规律研究

分散元素在自然界含量很低,以分散状态存在,很少形成独立矿物和独立矿床,因此对矿床中伴生分散元素研究有重要的理论和现实意义。本次工作通过解剖康滇地轴东缘典型铅锌矿床——四川天宝山、四川大梁子和云南会泽,利用常规显微镜观察、电子探针分析和等离子质谱分析手段,分析研究了矿床中矿物和矿石中的分散元素镉锗镓赋存状态和富集规律,总结了分散元素镉锗镓的空间分布规律:由西向东,即自天宝山到大梁子到会泽,分散元素镉锗镓的含量有富镉-富镉镓-富锗的变化规律。

The Research of Occurrence State and Enrichment Law of Associated Dispersed Elements Gd,Ge and Ga of Typical Lead-Zinc Deposits in the Eastern Edge of Kangdian Axis,China

The content of the dispersed elements is very low in the nature. They are existence with dispersed state. They are seldom to form independent minerals and deposits. Therefore,it has important theoretical and practical significance to research the associated dispersed elements in deposits. This work researched the typical lead-zinc deposits in the eastern edge of Kangdian Axis (Tianbaoshan,Daliangzi and Huize).Used on the observation of the common microscope and the means of electron microprobe analysis and ICP-MS analysis,we analyzed the occurrence status and enrichment law of dispersed elements of Cd,Ge and Ga,summed up the distribution rule of dispersed elements of Cd,Ge and Ga. From west to east,that is,from Tianbaoshan to Daliangzi to Huize,the content of the dispersed elements of Cd,Ge and Ga have alternation law of enrich Cd and Ga to enrich Cd to enrich Ge.
