The Saar-Nahe Basin is a late Variscan intermontane basin that developed on the site of an earlier island arc, the Mid-German Crystalline Rise. Within the c. 6500m-thick continental sedimentary fill of the basin, a large variety of igneous rocks was emplaced over a period of c. 4 Ma from 296 to 293 Ma as high-level intrusions and lava flows, extrusive domes, diatremes and pyroclastic deposits, ranging in composition from basalt and basaltic andesite to rhyodacite, rhyolite and trachyte. Composite intrusive-extrusive complexes consist of andesite, rhyodacite and alkali feldspar trachyte with up to 10 wt% K2O. The geochemical characteristics of the most primitive mafic magmas indicate a slightly enriched upper mantle source modified by subduction-related fluids. Nd-Sr-O isotope data indicate that crustal contamination was important in the petrogenesis of the more differentiated magmas.
