摘    要:用ICP-MS测定了黔西南烂泥沟和丫他卡林型金矿床石英流体包裹体中的Co、Ni、Cu、Pb、Zn和Pt等元素的含量。结果显示,不同成矿阶段石英流体包裹体中均有较高的Co、Ni、Cu、Pb和Zn含量,并首次发现卡林型金矿床成矿流体中富含Pt。据此认为基性火山岩可能是卡林金矿床成矿物质的重要来源之一。

关 键 词:流体包裹体  微量元素  卡林型金矿床  贵州  成矿流体  基性火山岩

Abstract:Inductively coupled plasma mass spectrometry (ICP MS) is used to determine trace elements in fluid inclusions. Quartz separated from the Lannigou and Yata Carlin type gold deposits, southwestern Guizhou Province, is prepared by the decrepitation leach method. The leachates are analyzed by ICP MS,using conventional sample introduction. The results indicate that the concentrations of Co, Ni, Cu, Pb, and Zn in fluid inclusions are much higher than the quantification limits of the blank solution. It is interesting to note that the fluids associated with gold mineralization at the Lannigou and Yata gold deposits have high concentration of Pt, which implies that the basic volcanic materials may be involved in the formation of the Carlin type gold deposits, southwestern Guizhou Province.
Keywords:fluid inclusion  trace element  ICP  MS  Carlin  type gold deposit  Guizhou Province
