Summary:The late Devonian or Lower Carboniferous Russ Conglomerate contains granitic pebbles which yielded early Ordovician U-Pb ages. Similar rocks with granite pebbles of approximately the same age occur in the Saxothuringian zone of Germany (NE-Bavaria), where the granitic rocks are also found as shallow-level intrusions into early Palaeozoic rift sequences. In Bavaria, uplift and erosion of the granites and their country-rocks occurred together with the extrusion of intraplate basalts, during a second extensional episode (Frasnian). The presence, in the Vosges, of Ordovician granite pebbles in a conglomerate associated with basaltic volcanics confirms the classical correlation between northern Vosges and the Saxothuringian of Germany.
