Trace element composition of quartz from the Variscan Altenberg?Teplice caldera (Krušné hory/Erzgebirge Mts, Czech Republic/Germany): Insights into the volcano-plutonic complex evolution

Popis výsledku v původním jazyce

The internal structures and appropriate trace-element distribution of quartz grains were studied using laser ablation ICP-MS technique combined with a hot- and scanning cathodoluminiscence analysis. Studied Variscan magmatic suite is located in the Altenberg-Teplice Caldera (eastern Krušné Hory/Erzebirge - along the Czech Republic/Germany border) and is composed from co-magmatic volcanics (peraluminous basal rhyolite and associated dacite, overlying three units of subaluminous Teplice rhyolite and granite porphyry), and plutonic granites (two intrusions of A-type biotite and zinnwaldite granites). The trace-element distribution in granite prorphyry and rhyolite quartz shows distinct zonality in cathodoluminiscence images and chemical compositions: coreis poor in Ti, outer rim zones enriched with Ti, whereas Al records an opposite trend. In contrast, quartz from granites are very weakly zonated or homogenous. Based on the chemical composition of quartz and their zoning, we assume that
