The data presented are whole-rock geochemical analyses (major and minor elements, REE) of highliy deformed and metamorphosed rocks of the Middle and Eastern Erzgebirge nappe stacks. Geochemical discrimination was used to identify the protolith nature of a sample series representing metasedimentary, metagranitoidic, metarhyolitic, and metabasaltic rock types. Discrimination between para- and orthogneisses was also supported by mathematical factor analysis. According to new geochronological data, ages of the sample series range between Neoproterozoic to Ordovician. Analyses with different methods (ICP, AAS, XRF, OES, WET) were made between 1979 and 1991 in different laboratories of the German Democratic Republic (GDR) and the early GFZ German Research Centre for Geosciences. Economical constraints limited the capacity of and access to labs, and also available techniques in the GDR - limiting the spectrum of elements to be analysed, especially that of REE, as well. Switching from lab to lab (see table) became a neccessary tool. Despite these problems, all data proved to be comparable. This also applies in comparison to data from later used techniques (ICP, from 1991 on) on some additional sample material, regardless of its higher resolution. In few cases, detection limits have not been communicated (see template). The data are reported with the EarthChem Templates (https://doi.org/10.26022/IEDA/112263).

The data presented are whole rock geochemical analyses (major and minor elements, REE), of Neoproterozoic turbiditic greywackes, Cadomian anatexitic rocks with metabasaltic inclusions, and post-collisional granodiorites. The data publication presents geochemical classification of the source regions of greywacke outcrops across the Lusatian massif, supported by microscopic lithoclast analysis. Discrimination further served to evaluate formerly assumed different geotectonic settings during age-different orogenic processes in the Western, as well as in the Eastern part of Lusatia. This was applied to the turbiditic greywackes, adjacent anatectic to granodioritic rocks, and mafic volcanogenic intercalations within the greywackes (tuffitic material) and the anatexites.

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 (Höhn et. al., 2018, doi:10.1007/s00531-017-1497-2) in the Table 2 'W-domain'.

The 47 km long KTB Line 1 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects. The network of lines consists of two DEKORP profiles, DEKORP 4N and its appendix 4Q, and six shorter KTB profiles, KTB 8501 – 8506, arranged in the form of a grid parallel and perpendicular to the main tectonic lineaments. high-fold near-vertical incidence vibroseis acquisition. The main focus was on the crustal structure of the central Mid-European Variscides down to the Moho and the uppermost mantle and, in particular, on the suture between the Moldanubian Zone and the northward adjacent Saxothuringian Zone as well as on the metamorphic Zone of Erbendorf-Vohenstrauss. The array of the KTB profiles represents the pre-cursor of the 3-D seismic survey ISO 1989 (Integrated Seismics Oberpfalz). Details of the experiment, first results and interpretations were published by DEKORP Research Group (1987, 1988). Results discussed together with the drilling site were presented in a number of works which can be found in Emmermann & Wohlenberg (1989). The Technical Report of KTB 8501 gives complete information about acquisition and processing parameters. The European Variscides, extending from the French Central Massif to the East European Platform, originated during the collision between Gondwana and Baltica in the Late Palaeozoic. Due to involvement of various crustal blocks in the orogenesis, the mountain belt is subdivided into distinct zones. The external fold-and-thrust belts of the Rhenohercynian and Saxothuringian as well as the predominantly crystalline body of the Moldanubian dominate the central European segment of the Variscides. Polyphase tectonic deformation, magmatism and metamorphic processes led to a complex interlinking between the units. The Saxothuringian represents the infill of a Cambro-Ordovician basin. The Moldanubian contains blocks of pre-Variscan crust and their Palaezoic cover. During the Variscan orogeny the Moldanubian crust was thrust toward the northwest over the Saxothuringian foreland. Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The WSW – ENE striking line KTB 8501 is located ca. 12 km north of the KTB borehole. From southwest to northeast KTB 8501 crosses KTB 8504, DEKORP 4N, KTB 8505 and KTB 8506. As well as the lines KTB 8502 and 8503 the profile 8501 was arranged parallel to strike running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). The most important tectonic lineament, crossed by KTB 8501, is the NW-trending Franconian Line. The fault zone separates the crystalline Bohemian Massif from the foreland, which is covered by Mesozoic and Upper Palaeozoic sedimentary rocks (DEKORP Research Group, 1987).
The 50 km long KTB Line 4 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects. The network of lines consists of two DEKORP profiles, DEKORP 4N and its appendix 4Q, and six shorter KTB profiles, KTB 8501 – 8506, arranged in the form of a grid parallel and perpendicular to the main tectonic lineaments. The purpose of the investigations was to explore the planned target area for the Continental Deep Drilling Site in the Upper Palatinate with high-fold near-vertical incidence vibroseis acquisition. The main focus was on the crustal structure of the central Mid-European Variscides down to the Moho and the uppermost mantle and, in particular, on the suture between the Moldanubian Zone and the northward adjacent Saxothuringian Zone as well as on the metamorphic Zone of Erbendorf-Vohenstrauss.

Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The NNW-SSE trending line KTB 8504 runs ca. 15 km southwest from the KTB drill site, nearly parallel to KTB 8505, KTB 8506 and DEKORP 4N and perpendicular to KTB 8501 – 8503. The profile is located southwest of the Franconian Line inside the Permo-Carboniferous and younger sediments of the Mesozoic foreland, which is underlain by a westward continuation of the Erbendorf-Vohenstrauss Zone (DEKORP Research Group, 1988).

Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The ENE – WSW striking line KTB 8502 is located normally to the KTB lines 8504, 8505 and 8506 and to DEKORP 4N. The profile runs close to the area of the KTB drill hole, thereby crossing the DEKORP 3D survey ISO 1989. As well as the lines KTB 8501 and 8503 the profile 8502 was arranged parallel to strike, running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). In the southwest KTB 8502 crosses the Franconian Line, a fault zone which separates the crystalline Bohemian Massif from a foreland. Farther to the northeast KTB 8502 crosses metamorphic nappes and Variscan granites of the Erbendorf-Vohenstrauss Zone.

The WSW – ENE striking line KTB 8503 is located normally to the KTB lines 8504, 8505 and 8506 and to DEKORP 4N running ca. 16 km south of the KTB drill hole. As well as the lines KTB 8501 and 8502 the profile 8503 was arranged parallel to strike running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988).

The line is located ca. 9 km northeast from the KTB drill site, nearly parallel to KTB 8504, KTB 8506 and DEKORP 4N and perpendicular to KTB 8501 – 8503. The profile also crosses the DEKORP 3D survey ISO 1989.
