摘要
文章对与沉积岩容矿有关的热液广西高龙微细浸染型金矿、新疆霍什布拉克铅锌矿、广西盘龙铅锌矿和下雷锰矿等矿床硫化物进行硫同位素测定,硫同位素组成分别为-15.3‰^+15.6‰,-18.8‰^+24.2‰,-21.0‰^+26.4‰,-32.6‰^+32.2‰。硫同位素可以达到平衡(高龙、霍什布拉克、下雷),也可以没达到平衡(盘龙)。δ34SΣS值在+13‰^+28‰之间,表明与沉积岩容矿热液矿床中硫来源于海水硫酸盐还原硫,但不排除有岩浆硫的加入。
This paper conducted sulfur isotope assay on sulphides in deposits related to sediment-hosted hydro-thermal deposits such as Gaolong micro-disseminated Au deposit in Guangxi,Huoshibulake Pb-Zn deposit in Xinjiang,Panlong Pb-Zn deposit and Xialei Mn deposit in Guangxi,and the sulfur isotope compositions are respectively -15.3‰~＋15.6‰,- 18.8‰~＋24.2‰,-21.0‰~＋26.4‰ and -32.6‰~＋32.2‰. The sulfur isotope can be balanced （such as those in Gaolong,Huoshibulake and Xialei）,and it also can be unbalanced （such as that in Panlong）.δ34 SΣS value varies between ＋13‰ and ＋28‰.It is suggested that the source of sulfur in sediment-hosted hydrothermal deposits derives from seawater sulfate reduction,and magma-degassing sulfur may have been involved in the process.
