The sampling area is located east (E-domain) and west (W-domain) of the Münchberg gneiss massif, NE Bavaria. Germany. Major and trace element compositions and Sr, Nd, and Pb isotope composition of a selected subset of Ordovician samples and post- Devonian samples of mafic igneous rocks are documented in the Table 1 'E-domain'. Sr, Nd, and Pb isotope composition of selected mafic igneous rocks from the W-domain of Ordovicician, Silurian, and Devonian age are documented together with the previously analysed Rb-Sr, Sm-Nd, U-Th-Pb concentrations from Höhn et al. (2018, doi:10.1007/s00531-017-1497-2) in the Table 2 'W-domain'.The project was performed without external funding and proper project title. Sample collection of the E-domain is based on different student's field practicals in the Münchberg area under supervision of Gerhard Franz. Samples of the W-domain are a subset of samples described by Höhn et al. (2018, doi:10.1007/s00531-017-1497-2).
