Interpretation of paleoredox environments based on the trace-element content of authigenic calcites

Interpretation of paleoredox environments based on the trace-element content of authigenic calcites
This study develops an approach that can be used to interpret redox conditions in paleo-groundwaters based on the trace-element content of late-stage fracture calcites. Ranges in total concentrations of selected cations in groundwaters coexisting with calcite are first calculated using analytical data on mineral chemistry and experimentally determined ...
