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.
The dataset contains major and trace element data as well as radiogenic W isotope data for >3.5 Ga felsic to ultramafic volcanic rocks from the Kaapvaal and Singhbhum Cratons. For the Kaapvaal Craton additional 143Nd data is provided. Major elements were analysed by XRF at Würzburg University and the School of Geological Sciences, University of KwaZulu-Natal; trace elements by ICP:MS at Georg-August Universität Göttingen, Department for Geochemistry and Isotope Geology; radiogenic W and 143Nd isotopic data were measured by ICP:MS-MC at Georg-August Universität Göttingen, Department for Geochemistry and Isotope Geology.
These data are published as a supplement to Messling et al. (2023), Mobilization of Tungsten in Greenstone Belts of the Archaean Kaapvaal and Singhbhum Cratons, Geochemistry, Geophysics, Geosystems, 24(2),(https://doi.org/10.1029/2023GC011161). A subset of these data were previously published in Jodder (2021), The geology of the Daitari Greenstone Belt, Singhbhum Craton, India - insights into early life 3.5 Ga ago, Doctoral thesis, University of Johannesburg, https://hdl.handle.net/10210/477262
