Supereruptions and caldera formations are rare but catastrophic events in Earth’s history, and their underlying processes and internal structure often remain inaccessible. This study presents results from a 648 m deep, continuously cored profile (drilling B1/19S) through the caldera fill deposits of the Lower Permian Wurzen Volcanic System (WVS) at Großsteinberg quarry (Grimma, Saxony, Germany), offering valuable insights into...

The late Carboniferous/early Permian post-collisional rhyolites (305–285 Ma) that formed in Central Europe have generally similar whole rock compositions to that of older Late-Variscan rhyolites (330–310 Ma). However, data compilation combining zircon age with the chemical composition of rhyolites from 20 units shows a trend of increasing zircon saturation temperature with decreasing age. This trend is particularly well identi...

Extensional tectonics in the Late Paleozoic Central Europe was accompanied by rift magmatism that triggered voluminous intracontinental caldera-forming eruptions. Among these, the Lower Permian Rochlitz Volcanic System (RVS) in the North Saxon Volcanic Complex (Eastern Germany, Saxony) represents a supereruption (VEI 8, estimated volume of 1056 km 3 ) of monotonous rhyolites followed by monotonous intermediates. Mapping, petro...
