Ruthenium and Tungsten isotopic composition of ocean island basalts and refrence materials

The dataset includes Ruthenium and Tungsten isotope data for mafic to ultramafic lava associated with the Hawaii, Réunion, Galápagos and Iceland plume systems. The data is supplemented by Ru isotope data for reference materials (OREAS 684) picrite derived from the upper mantle (Gönnern Quarry, Hessia) lherzolite preidotites (Eifel) and Eoarchean dunites (Isua, Greenland). The data are supplementary to: Messling, Nils; Willbold, Matthias; Kallas, Leander; Elliott, Tim; Fitton, J. Godfrey; Müller, Thomas; Geist, Dennis (submitted) Core leakage revealed by Ru and W isotope systematics in ocean island basalts. Submitted to Nature

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.

Global mantle clinopyroxene data (major and trace elements)

Compilation of global major and trace element compositional data for clinopyroxenes from mantle xenoliths from 972 locations worldwide, originally downloaded from the GEOROC database (https://georoc.eu/; accessed 14 July 2020). Each location includes multiple samples and analyses. To exclude unreliable samples, we used only clinopyroxenes with 40–60 wt.% SiO2, <40 wt.% MgO, <30 wt.% FeOT, <26 wt.% CaO, and oxide totals of 98.5–101.5 wt.%. Elements missing from >60% of the entire dataset were not considered. The dataset contains 21,605 observations (rows) corresponding to clinopyroxene major element analyses (SiO2, TiO2, Al2O3, Cr2O3, FeOT, CaO, MgO, MnO, and Na2O), and 2,967 rows of trace element analyses (including Sc, Ti, V, Cr, Ni, Rb, Sr, Y, Zr, Nb, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, Pb, Th, and U). Database as published in Qin et al. (2022).

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).

In-situ Karbonatisierung von Platinminenabraum - Mineralen zur CO2 Sequestrierung

Im Rahmen des Projekts werden Pyroxenite aus dem Bushfeldkomplex in Südafrika mineralogisch charakterisiert und anschleißend bzgl. ihres Verhaltens geegnüber Karbonatisierung untersucht. Der Minenabraum der Platinminen stellt ein mögliches Material zur In-situ Karbonatisierung dar. Die Arbeiten laufen in Kooperation mit Prof. Altermann(Univ. Pretoria) und Prof. Stark (Uni Darmstadt). Zur Untersuchung der Gesteine werden die Mineralanteile separiert und zur Mineralkarbonatisierung vorbereitet.
