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.%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)。δ34 SΣS 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。
