【摘要】：為研究福建邱村金礦的礦床成因,對(duì)圍巖蝕變、礦石礦物成分及流體包裹體進(jìn)行了研究。圍巖蝕變研究表明,金礦化與石英(玉髓)-伊利石-黃鐵礦-碳酸鹽礦物組合相關(guān),為一套典型低硫型淺成低溫?zé)嵋何g變組合。電子探針成分分析顯示,銀金礦中金含量為62%~69%,銀含量為28%~33%,金的成色平均為674。包裹體巖相學(xué)及顯微測(cè)溫結(jié)果顯示,含金石英脈中以富液相兩相包裹體為主,偶見(jiàn)少量富氣相包裹體;富液相兩相包裹體的均一溫度為180~250℃,鹽度為0.5%~3.0%Na Cleq。激光拉曼測(cè)試表明,包裹體氣相成分以水為主。上述結(jié)果均表明邱村金礦床應(yīng)屬于低硫型淺成低溫?zé)嵋旱V床。
[Abstract]:In order to study the genesis of Qiucun gold deposit in Fujian Province, the alteration of surrounding rock, mineral composition of ore and fluid inclusions were studied. The study of wall rock alteration shows that gold mineralization is related to quartz (chalcedony, Illite, pyrite and carbonate mineral assemblage), and is a typical low-sulfur epithermal hydrothermal alteration association. The electron probe analysis showed that the gold content in the silver gold deposit was 622 ~ 6910 and the silver content was 28 ~ 33. The average gold color was 674. The results of petrography and microthermometry show that the rich liquid phase two phase inclusions are dominant in gold bearing quartz veins, and a few rich gas inclusions are occasionally found, and the homogenization temperature of liquid rich two phase inclusions is 180 ~ 250 鈩，
