WebNov 29, 2024 · Platinum-group element (PGE) geochemistry of arc-related magmas can be used to constrain the timing of sulfide saturation, which plays a critical role in the chalcophile element fertility of evolving magmatic systems. In this study, we provide new major and trace elements, PGE, Re and Au data for the shoshonitic suite (from basalt to rhyolite) of the … WebOrthophosphate was the more effective inhibitor, yielding 33–96% less lead release than matched controls. Orthophosphate inhibition was attributed to conversion from lead(II) carbonate to hydroxylpyromorphite (Pb 5 (PO 4) 3 OH) and adsorption to lead(II) carbonate in the absence of a phase conversion (i.e., at pH 9 with 50 mg C per L ...
