U-Pb of apatite from Maroldsweisach, Bramberg, Zimmerau Süd and Fuchslöcher@en

In the project \"Geochemistry and geochronology of the Heldburg dyke swarm, Central European Volcanic Province\" we conducted geochemical and geochronological investigations on mafic dykes and former magma chambers of the Heldburg dyke swarm. The latter is part of the Central European Volcanic Province and positioned in the South of Thuringia and the North of Bavaria (Germany). It consists of several hundred mafic NNE-SSW striking dykes with an usual thickness of <1 m and few former magma chambers. All of these have an atypical position within the Central European Volcanic Province located away from Hercynian massifs and major rift axes and were hitherto poorly investigated. […]
