Major and trace element concentrations and Sr, Nd, Hf, Pb isotope ratios of global mid ocean ridge and ocean island basalts

Major and trace element concentrations and Sr, Nd, Hf, Pb isotope ratios of global mid ocean ridge and ocean island basalt whole-rock compositions from the GEOROC and PetDB databases (2021-2022). Key publications: Stracke, A., Willig, M., Genske, F., Béguelin, P., & Todd, E. (2022). Chemical Geodynamics Insights From a Machine Learning Approach.

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. Nature Communications, 12(1), 2045. https://doi.org/10.1038/s41467-021-22323-9

Chemical analyses of the Eastern Australian Potassic Suite: Whole-rock major, trace, and volatile element geochemistry

These data represent the most complete set of analyses of the Eastern Australian Potassic suite. The data include whole-rock major-, trace-, and volatile-element analyses including loss-on-ignition measurements for 48 samples from 21 spatially distinct leucite-bearing volcanic surface expressions. These expressions range from topographically prominent volcanic edifices and mounds, through to lava flows, with four sample locations (8 samples total) coming from active quarry sites. Location and elevation data as well as methods used are provided. Trace-element data are available for 45 samples and include a total of 41 elements, while volatile-element data are available for 47 samples. All samples have major element analyses (10 elements). This is an update on the dataset provided in version 1 (https://doi.org/10.25625/AB5PLG). Additional information on the sample texture, description, and analytical methods has been added. This update also rectifies mismatches between some trace-element analyses and the corresponding samples. Data for Sn have been removed due to poor accuracy and precision.
