Sulfur Isotopic Composition of Sulfides in Skarn and Vein Mineralization of the Dal’negorsk Ore Region (Primorye)

Resumo

The S isotopic composition in the ore-forming minerals galena and sphalerite was studied in different Ag–Pb–Zn deposits of the region. It was pointed out that the δ³⁴S modal values range from–1.2 to +6.7‰ in the minerals with a positive value for the skarn mineralization. In the flyschoid formation, the vein-type mineralization is characterized by negative and positive values. The narrow range of δ³⁴S values indicates the marginal-continental type of the mineralization and the multiple origins of its sources.
