Abstract

Abstract: The tungsten deposit area in Kuimei Mountain is located at the composite zone formed by the eastern segment of Nanling E-W trending structural belt and the southern segment of NE-NNE trending structural belt in Wuyi Mountain. The mining area is characterized by the coexistence of quartz vein-type wolframite ores and skarn-type scheelite ores.This study determines the isotopes of hydrogen, oxygen and sulfur found in the wolframite,quartz and chalcopyrite ores from a quartz vein-type wolframite deposit.The results show that the δ¹⁸O values of wolframite range from 4.4‰ to 5.7‰. The δ¹⁸O values of quartz veins range from 12.3‰ to 13.4‰,and the calculated δ¹⁸O_H₂O values of quartz veins range from 1.42‰ to 6.19‰.The δD values of quartz inclusions in ore-bearing quartz veins range from －49‰ to －67‰, and the δ³⁴S values of chalcopyrite concentrate between －3.2‰ and 0.3‰. The findings indicate that the metallogenic fluid for the main mineralization period of tungsten ores in Kuimei Mountain is not only originated primarily from magmatic water but also subject to influences from atmospheric precipitation. It is also found that the origin of the metallogenic fluid’s sulfur source is primarily magmatic.

摘要： 岿美山钨矿区地处南岭EW向构造带东段与武夷山NE-NNE向构造带南段的复合部位,是南岭地区石英脉型黑钨矿体和矽卡岩型白钨矿体共存的一个大型钨矿区。文中对石英脉型黑钨矿体中黑钨矿、石英和黄铜矿进行了H、O和S同位素测定,结果显示黑钨矿的δ¹⁸O值为4.4‰～5.7‰;石英的δ¹⁸O值为12.3‰～13.4‰;计算出石英中水的δ¹⁸O_H₂O的值为1.42‰～6.19‰;矿脉中石英包裹体δD值为－49‰～－67‰;黄铜矿的δ³⁴S值集中分布于－3.2‰～0.3‰。研究结果表明:岿美山钨矿主成矿期成矿流体主要来源于岩浆水,同时受到大气降水的影响;成矿流体中S来源单一,主要为岩浆来源。
