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 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.

The geology of the Saxon Granulite Massif and particularly its metamorphic history is a matter of on-going (passionate) discussions that resulted in several concurring tectonic models. Meanwhile, less attention has been paid on the pre- and post-metamorphic evolution of this area. Comprehensive compilation of available data and presentation of new geochemical and geochronological results help reconstructing the evolution of this part of the Central European Variscides and point towards partial involvement of non-Gondwanan crustal components during the Carboniferous. Therefore, at least parts of the Saxon Granulite Massif represent exotic fragments in the Saxothuringian Zone. Data given here comprises U-Th-Pb and Hf isotopic analyses of rocks from the Saxonian Granulite Massif.
