GEOSCRAPE zircon database

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.

New geochemical analyses on samples drilled on the mid-Norwegian margin during IODP Expedition 396, ODP Leg 104 and DSDP Leg 38

New major and trace element data on samples collected during the IODP (International Ocean Discovery Program) Expedition 396, ODP (Ocean Drilling Program) Leg 104, and DSDP (Deep Sea Drilling Project) Leg 38 on the Vøring margin, including 209 whole rocks analyses on hard rock samples (basalt, granite, andesite, dacite and rhyolite), 13 whole rock data on ash layers, and 381 in situ pXRF analyses on basaltic rocks.

Iran and SE Anatolia Meso-Cenozoic igneous rock compositions

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).

Global distribution and composition of Neogene-Quaternary intraplate volcanic rocks

Global database of  >20, 000 geochemical analyses of Neogene-Quaternary intraplate volcanic rocks. The database collates major, trace element and Sr-Nd-Pb isotopic data for whole-rock samples <20 Ma old that were published between 1990 and 2020. Database as published in Ball et al. (2021). Key publication: Ball, P. W., White, N. J., Maclennan, J., & Stephenson, S. N. (2021). Global influence of mantle temperature and plate thickness on intraplate volcanism.

Magmatic rock compositions from the Circum-Mediterranean Anorogenic Cenozoic Igneous province

Collection of published and new major and trace element and Sr–Nd–Pb isotopic data (more than 7800 samples) for the magmatic rocks from the Circum-Mediterranean Anorogenic Cenozoic Igneous province compiled by Lustrino & Wilson (2007).

Geochemical compositions of igneous rocks of the Central Andean orocline

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. Related key publication: Mamani, M., Wörner, G., & Sempere, T. (2010). Geochemical variations in igneous rocks of the Central Andean orocline (13°S to 18°S): Tracing crustal thickening and magma generation through time and space.
