Redox conditions in Late Permian seawater based on trace metal ratios in fluid inclusions in halite from the Polish Zechstein Basin

Previous studies have confirmed that primary fluid inclusions in halite record and preserve information concerning the major ion chemistry of seawater. Here, we determine ratios of redox sensitive trace metals (Fe, Mn, V, Mo, U) in paleo-seawater trapped as primary fluid inclusions in halite from two boreholes (Przyborów IG3, Gorzów Wielkopolski IG1) from the Polish sector of the European Southern Permian Basin and estimate the original seawater concentrations of the redox sensitive trace metals.
