Barium (Ba) shows a slightly right skewed log distribution. Its maximum amounts to 3330 mg/kg, whereas the values of more than 1000 mg/kg constitute less than 1 % of the total. The minimum is 10 mg/kg. The arithmetic average is 138 mg/kg, and the median is 90 mg/kg. The element is mainly related to baryte–fluorite vein mineralisation. Absolute concentrations are possibly underestimated due to limited solubility of Ba in aqua regia used for the analyses. Areas of high concentration (Ba 400 mg/kg) form an arc between the Freiberg mining district and Dippoldiswalde where barite mainly accompanies the exploited polymetallic and Sn deposits as gangue. Apart from this arc, a circular area of 3 km diametre with elevated Ba coincides with fluorite and baryte veins NW of the Marienberg deposit in the central Erzgebirge. Further Ba elevations mark the baryte deposit of Brunndöbra, the baryte veins west of the Bergen granite, the deposit of Grünberg north of Augustusburg, and an area NW of the AueBärengrund deposit, where baryte was observed in debris during stream sediment sampling. Lower elevations of Ba 160 mg/kg characterise the gneiss cupola of Schwarzenberg, the baryte–fluorite deposits of Langenstriegis, NiederschlagBärenstein, and the area NW and SW of Oelsnitz dominated by Devonian sediments and volcanics. The lowest concentrations of barium (Ba weiterlesen
