The initial phase of the Late Carboniferous Altenberg-Teplice Volcanic Complex: Volcanosedimentary evolution of the Schönfeld–Altenberg Depression Complex

Popis výsledku v původním jazyce

The Altenberg–Teplice Volcanic Complex comprises an early volcano-sedimentary succession preserved in the Schönfeld–Altenberg Depression Complex (SADC), partly covered by voluminous ignimbrites and lavas of the Teplice Rhyolite. For the first time, pre-existing and new data sets of the SADC have been synthesized from outcrops and wells located in Germany and Czech Republic. The SADC is subdivided into the Schönfeld-Pre-Eruptive Sediments (SPES), and the volcanosedimentary successions of the Lower Schönfeld Complex (LSC) and the Upper Schönfeld Complex (USC). The SPES is deposited on metamorphic basement and consists of sandstones and conglomerates containing different types of metamorphic clasts; it also contains carbonaceous layers. The LSC starts with widespread, fine-grained ignimbrites of rhyolitic composition (maximum thickness of 153 m near Hermsdorf). The explosive phase of the LSC is followed by the formation of (trachy-)dacitic lava(s) and subvolcanic bodies. The USC starts with coarse-grained talus deposits, dominated by metamorphic clasts, indicating a major tectonic activity. Lavas and pyroclastic rocks comprises the USC in the southern part, whereas in the Schönfeld area, lava dome explosion-related pyroclastic and sedimentary deposits, alternating with carbonaceous layers, prevail. The SADC volcanic rocks are classified as dacites, trachydacites and rhyolites, having unusually elevated concentrations of Ti and compatible elements like Cr and V. Compared to the LSC, the USC volcanics show a less alkaline affinity.
