Crustal vs. mantle contributions in the Erzgebirge/Krušné hory Mts. magmatism: Implications for generation of zoned, A-type silicic rocks in the late-Variscan Altenberg-Teplice Caldera, Central Europe

Lithos, 2021
Abstract Late-Variscan (S-, A-type) granites and rhyolitic ignimbrites/lavas (~325 Ma) of the Altenberg-Teplice Caldera (Erzgebirge/Krusne hory Mts., NW Bohemian Massif) were investigated by using mineral and whole-rock chemistry and Nd–Pb isotopic systematics. Focus was given to the normally zoned Teplice Rhyolite (TR) volcanic successions and, to a

Magmatism of the late Variscan intermontane Saar-Nahe Basin (Germany): a review

Geological Society, London, Special Publications, 2004
Abstract 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.
