AbstractStudies of noble gases in seafloor sulfide deposits are an important tool for understanding the origin of oreforming fluids, both enabling the determination of noble gas sources and revealing the degree of fluid-rock interaction and mantle degassing. The noble gas concentrations and isotopic compositions of 27 sulfide, 3 sulfate, and 2 opal mineral aggregate samples have been studied in different hydrothermal fields from the East Pacific Rise, Mid-Atlantic Ridge, Central Indian Ridge, Southwest Indian Ridge, and North Fiji Back-Arc Basin. The helium concentrations and isotopic ratios in the sulfide aggregate samples are variable (He-4 0.12 to 22 x 10(-8) cm(3) STP/g; He-3/He-4 similar to 0.6 to 10.4 R-a), and most of the sulfide helium concentrations are higher than those in the opal mineral samples (He-4 0.017 and 0.028 x 10(-8) cm(3) STP/g), suggesting that the low-temperature fluids have lost their mantle helium during cooling. The helium of high (>7 Ra), medium (1-7 Ra), and low (approximate to 1 Ra) He-3/He-4 ratio samples is derived mainly from the MORB or OIB mantle by magma degassing, from mixing between hydrothermal fluid and seawater during ore-forming processes, and from ambient seawater, respectively. The high He-3/He-4 ratios (>7 Ra) of sulfides imply that high-temperature sulfides retain the helium isotopic compositions of the primary hydrothermal fluid, whereas low-temperature sulfides, sulfates, and opal minerals do not.
