“…Sulfur in VHMS deposits usually comes from: (1) a magmatic source (Ohmoto, 1996) through a direct contribution from a vapor-rich magmatic fluid (Ohmoto, 1986;Stanton, 1990;Gemmell and Large, 1992;Sillitoe et al, 1996;Herzig et al, 1998, Galley et al, 2000Solomon et al, 2004) or leaching from subsurface magmatic rocks (Ohmoto and Goldhaber, 1997); (2) an inorganic reduction of seawater sulfate during a deep circulation process (Ohmoto et al, 1983;Solomon et al, 1988); and (3) a bacterial reduction of seawater sulfate (Sangster, 1976;Cagatay and Eastoe, 1995).…”

Sulfur isotope data from sulfide and sulfate minerals have been measured from the two typical examples of the Permian volcanic-hosted massive sulfide (VHMS) deposits at the Tasik Chini district in the Central Belt of Peninsular Malaysia. In this study, we present the sulfur isotope data for 33 sulfide minerals and 23 barite samples from two VHMS deposits in the Tasik Chini district. Sulfides show a narrow range of sulfur values from -2.9‰ to +8.30‰, which can be interpreted to be derived from a mixed sulfur source of reduced seawater sulfate with the possible addition of magmatic sulfur. Sulfate sulfur in barites yields a δ 34 S range between 11‰ and 22‰, which is comparable to that of Permian seawater sulfate. Sulfur isotope results obtained for the VHMS deposits in the Tasik Chini district suggest that the source of ore fluids during the formation of the Tasik Chini VHMS deposit is a seawater-dominated fluid with probably minor magmatic fluid input. This is similar to VHMS associated with ancient and modern submarine hydrothermal systems.

extensional tectonic regime during subduction. Major lineaments and circular structures exerted fundamental controls on the locations of VMS deposits in the eastern Pontide district. Age determinations indicate that almost all the deposits in this region formed in a restricted time interval between ca. 91.1 and 82 Ma. The sulfur isotope compositions of the ore-forming fluids are consistent with those of fluids derived from modified seawater.

“…Three main sources of sulfur to precipitate sulfides in VMS deposits are inferred: 1) inorganic reduction of seawater sulfate; 2) magmatic sulfur, either from a direct contribution from a vapor-rich magmatic fluid or after leaching of the volcanic host rocks; and 3) sulfur from microbial activity in reduced sediments by means of bacterial sulfate reduction (Sangster, 1976;Ohmoto, 1986;Solomon et al, 1988Solomon et al, , 2004Stanton, 1990;Çagatay and Eastoe, 1995;Shanks III et al, 1995;Ohmoto and Goldhaber, 1997;Herzig et al, 1998;Hoefs, 2009;Brueckner et al, 2015).…”
