Some additional references to S and O isotopes in sulfates formed
from pyrite oxidation:

ENVIRONMENTAL GEOCHEMISTRY OF SULFIDE OXIDATION, ACS Symposium Series 550.
pp. 481-514. (includes compilation of previously published data, some
newer data, and some re-interpretations of data in 1984 publications)

Alpers, C.N., et al., 1992, Chem. Geol., v. 96, pp. 203-226
(documents relatively heavy 18-O in aqueous sulfate, alunite
and jarosite in an Australian playa setting, where partial exchange
of 18-O between sulfate and water may have taken place over
hundreds of years at pH < 4.)
