title = "Sulphur geodynamic cycle",
abstract = "Evaluation of volcanic and hydrothermal fluxes to the surface environments is important to elucidate the geochemical cycle of sulphur and the evolution of ocean chemistry. This paper presents S/3 He ratios of vesicles in mid-ocean ridge (MOR) basalt glass together with the ratios of high-temperature hydrothermal fluids to calculate the sulphur flux of 100 Gmol/y at MOR. The S/3 He ratios of high-temperature volcanic gases show sulphur flux of 720 Gmol/y at arc volcanoes (ARC) with a contribution from the mantle of 2.9%, which is calculated as 21 Gmol/y. The C/S flux ratio of 12 from the mantle at MOR and ARC is comparable to the C/S ratio in the surface inventory, which suggests that these elements in the surface environments originated from the upper mantle.",

note = "Funding Information: We would like to thank Dr. Paul Middlestead of the University of Ottawa for cooperating in the analyses of sulphur isotopes in MOR basalt vesicles. CL DR01 and CH31 DR12 were supplied by Dr. Bernard Marty of Universit{\'e} de Lorraine. KH10-6 DR15-glass and KH10-6 DR16-glass were supplied by Dr. Hiroshi Sato of Senshu University. RY380-R03b and 418R002 were supplied from the sample archives of JAMSTEC, retrieved from following cruises under international projects or co-operations: MODE{\textquoteright}98 and RidgeFlux. This work was partly supported by a Grant-in-Aid for JSPS Fellows (25-6922). T.K. is a JSPS Research Fellow.",
