Fig. 1From: How well suited are current thermodynamic models to predict or interpret the composition of (Ba,Sr)SO4 solid-solutions in geothermal scalings?Backscattered electron SEM micrograph of the intact scaling surface. Lamellar (Ba,Sr)SO4 crystals appear in grey, the close to idiomorphic Galena (PbS) crystals appear in light grey Back to article page
