Formation and significance of laurionite in geothermal brine

Abstract

15The metal lead (Pb) is an environmentally significant, frequently occurring element in 16 geothermal brines. It was found to precipitate from saline fluids predominantly as laurionite 17 (PbOHCl) forming one of the most dominant scaling minerals identified at the geothermal site 18 Groß Schönebeck (Germany). In this study, its formation conditions and relevance for the
