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.
Analyses with different methods (ICP, AAS, XRF, OES, WET) were made between 1987 and 1993 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 necessary tool. Despite these problems, all data proved to be comparable. This also applies 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 been communicated.
The data are reported with the EarthChem Templates (https://doi.org/10.26022/IEDA/112263) and as original data tables. The data description is provided in English and German.

This database contains a compilation of published zircon geochronology, chemistry and isotope data. The database was created through automated web scraping of the Figshare data repository. Data included U-Pb and Pb-Pb dating, Lu-Hf isotopes, trace element and rare earth element chemistry and isotopes. Where available, metadata on the analytical method, lithology, sample description and sampling coordinates are included. All analyses include a citation and doi link to the original data hosted on Figshare. See metadata table for descriptions of table headers. See associated manuscript for web scraping code.
Compilation of igneous rock compositions from Iran and SE Anatolia Meso-Cenozoic (ISA), including major, trace element and Sr-Nd-Pb isotopic data as published in Lustrino et al. (2021).
Compilation of more than 1500 major- and trace-element data points, and 650 Sr-, 610 Nd-, and 570 Pb-isotopic analyses of Mesozoic-Cenozoic (190–0 Ma) magmatic rocks in southern Peru, northern Chile and Bolivia (Central Andean orocline). This compilation was initially published by Mamani et al. (2010) and was based on selected data published up until 2009, combined with new data from that study.
