Two opposing effects of sulfate reduction on carbonate precipitation in normal marine, hypersaline, and alkaline environments: COMMENT

Sulfate reduction (SR) has been linked to carbonate mineral precipitation and has been invoked as a possible mechanism for microbialite formation ([Lyons et al., 1984][1]; [Kempe, 1990][2]). Although there is evidence to support the contribution of SR in carbonate mineral precipitation from both
