摘　　要：THE fine disseminated gold deposits in Yunnan-Guizhou-Guangxi triangle area in S. China occur in thesedimentary rocks and are not relative to magmatism in space and genesis. Many authors have studiedthese deposits and obtained different conclusions. This note makes the first systematic study on sulfur isotope compositions to further discuss possible sources of ore-forming materials. 1 Sulfur isotope composition Figure 1 shows variations of sulfur isotope compositions of 232 sulfide separats from various depositsand their host rocks. S S values of pyrite from Mid-Triassic Banna Formation strata in the Jinya ore district can be divided into two groups: -7.4‰ to -6.4‰ and 2.7‰ to 14.1‰. Pyrite from the Jinyadeposits has δ³⁴S values of -7.2‰-1.9‰, stibnite -6.7‰- -4.9‰ and arsenopyrite -4.1‰-
