Observations sur deux niveaux mineralises dans le Paleozoique inferieur des monts du Minervois (Montagne Noire, Aude); mineralisations, lithologie et stratigraphie; contribution au debat syngenese-epigenese

A sparsely mineralized zone consisting essentially of galena, pyrite, and barite occurs at the top of an upper Georgian (Cambrian) calcareous dolomite sequence in the Minervois mountains, southwestern Montagne Noire region, France, and can be followed for more than 12 kilometers. Its constant association with a particular lithofacies suggests that the mineralization is syngenetic. Another zone of galena and sphalerite mineralization is localized in recrystallized limestone and nodular calcareous schists, attributed to the middle Tremadocian, and can be followed for more than three kilometers. this zone also appears to begenetically correlative with sedimentologic and paleogeographic conditions.
