Abstract:The Yunnan Jinding Pb-Zn, celestite, anhydrite and pyrite super-large deposits are locate at the northern part of Lanpin basin, which is also rich in organic materials (Bitumen and heavy oil). The δ34SV-CDT values of anhydrite and gypsum are concentrated in +12‰~+16‰, similar to the Triassic marine sulfate (+15‰); The distribution of celestite deposits followed the anhydrite deposits, and its δ34SV-CDT values are ranged of +6~+26‰. Except for some relative lower δ34SV-CDT values which was formed by bacterial sulphate reduction during the primary diagenesis mineralizaion stage, the most of metal sulfides presented a “two-group” distribution characteristic, one group of δ34SV-CDT values is concentrated at -12‰~-20‰, about 30‰ lower than the δ34SV-CDT values of anhydrite; another group of δ34SV-CDT values is concentrated at -8‰~-2‰, about 20‰ lower than the δ34SV-CDT values of anhydrite. When the temperature of the main mineralization stage is around 200℃, the sulfur isotopic exchange level between aqueous sulfates and sulfides is 30‰, while the sulfur isotopic exchange level reaches to 20‰ at 300℃. This phenomenon is consistent with the “two-group” distribution characteristic of Jinding deposit, demonstrate that most of sulfur element involved in the deposit are mainly come from thermochemical sulphate reduction of organic matters in Trassic halosalt minerals. When the ore-forming fluids with cations of Pb2+, Zn2+and Sr2+ encounted hydrothermal solution with organic matters, CO2, H2S and sulphate in the nappe dome structure, the galenite and sphalerite were formed by Pb2+, Zn2+ with H2S, while the formation of celestite is in present of Sr2+ with SO42-. The Trassic marine stratum (87Sr/86Sr=0.70695~0.70845) is not the only source of strontium (87Sr/86Sr=0.707765~0.710553) in the halosalt ore deposits, also extraced from multiple stratums by ore-forming fluids, according to the strontium isotope values of celestite, anhydrite, brecciated limestone and metal sulfides. Because of contamination from the high ratio of strontium isotope in ore-forming fluids, the strontium isotope level in brecciated limestones and metal sulfides are significantly increased. A combination of halosalt minerals - organic matters (or oil gas) - metal sulfides maybe a universal law in economic geology.
