| 摘 要： | 分散元素铊成矿作用的相关研究近年来已经取得了重要进展,但矿床中铊的赋存状态研究仍有待深入.香泉独立铊矿床位于长江中下游成矿带北侧的皖东地区,该矿床中铊的赋存状态研究对拓展铊元素成矿研究具有重要意义.本文通过矿相学、微量元素地球化学、电子探针分析和X射线粉晶分析等方法,确定了香泉铊矿床中黄铁矿是铊的主要载体矿物.铊在黄铁矿中主要以类质同象形式替代铁进入黄铁矿晶格,其次以纳米级、次纳米级铊矿物颗粒形式产出. |

| Abstract: | Important progress has been made in the study of thallium mineralization in recent years,but its mode of occurrence in ore deposits remains to be further studied.The Xiangquan thallium deposit is located in eastern Anhui at the northern side of the Middle-Lower Yangtze valley metallogenic belt.Thallium in the deposit is recovered as an ore of thallium alone ;the study of the mode of occurrence of thallium in the deposit has great significance for expanding the study of thallium mineralization.By using the mineralographic method,trace element geochemical method,microprobe analysis and X-ray diffraction analysis,pyrite in the deposit is determined to be the main carrier mineral of thallium.In pyrite,thallium occurs as isomorphs replacing iron and entering the lattice of pyrite,and less commonly it occurs as nano-and subnano-sized grains of thallium minerals. |
| Keywords: | Xiangquan Thallium deposit Pyrite Mode of occurrence Anhui |
