| Abstract: | Stable isotope studies of alunite have added a powerful tool for understanding geochemical processes in the surficial environment. Jarosite [KFe3(SO4)2(OH)6], like alunite, is a common mineral in the weathered portions of many sulfide-bearing ore deposits and mine drainages where its formation reflects acidic conditions produced by the oxidation of sulfides. This paper describes oxygen and hydrogen isotope fractionations in jarosite-water experiments over a temperature range of 100?? to 250??C and the extrapolation of the results to surface conditions. It also includes some general observations on the exchange reaction mechanism that are important for evaluating how well natural samples of jarosite retain primary isotopic compositions. -from Authors |
