摘要: The baryte occurrences along N to NW striking faults in Carboniferous and Devonian strata of the Ruhr area Rheinisches Schiefergebirge (Western Germany) are related still presently active chloridic, Ba-Sr bearing Na Na-Ca solutions. These originated from deeper seated waters which have their origin meteoric circulating fault systems, fossil Ba-rich Ordovician strata. Experimental results solubility behaviour BaSO4 SrSO4 water aqueous solutions can explain Ba Sr content these recent brines. A theory mineralisation is presented for believed find general application other regions.
