WebDestruction of original sedimentary features, intense silicification and carbonatization and pronounced groundwater-derived vanadium enrichment characterize the upper part of this alteration zone (Burton and Fralick, 2007). Groundwater systems, similarly to hydrothermal systems, are likely to amplify small sorption isotope effects.
