Description:
Cuttings of Lower and Middle Keuper sediments of the INFLUINS-drilling in the central Thuringian Syncline were geochemically analysed. Indications about shifting depositional environments are interpreted from ratios of whole-rock element contents. For the middle part of sandstone cycle S 2 high heavy metal contents imply precipitation of sufidic ores during a short marine interval. Element contents are compared with potential source rocks in the southern part of the Baltic Shield, in the Lausitz Anticline Zone, in the Erzgebirge, in the moldanubian part, in the broad sense, of the Bohemian Massif, in the Münchberg Gneiss Massif and the Fichtelgebirge. The geochemical coincidence of investigated Keuper sediments is highest with grantioid and gabbroic rocks of southern Scandinavia. Granodiorite rocks of the Lausitz are also possible sources, whereas granites of the Fichtelgebirge and the Bohemian Massif are less probable.
