The repository archives, publishes and makes accessible user-contributed, peer-reviewed research data in standardised form (EarthChem Team, 2022, https://doi.org/10.26022/IEDA/112263) that fall within the scope of the GEOROC database (https://georoc.eu). All submissions of new data will be considered for inclusion in the GEOROC database. It is hosted at GFZ Data Services through a collaboration between the Digital Geochemical Data Infrastructure (DIGIS) for GEOROC 2.0 (https://digis.geo.uni-goettingen.de) and the GFZ German Research Centre for Geosciences.
We report the titanium (Ti) stable isotope compositions (δ⁴⁹Ti) of Archean and Paleoproterozoic sanukitoids covering a range of ages and locations – the 2950 Ma high-Mg diorite suite from the Pilbara Craton, the ~2670 Ma Black Flag Group from the Yilgarn Craton, the ~2130 Ma Alto Maranhão suite from the São Francisco Craton, and two ~2115 Ma sanukitoids from the São Francisco Paleocontinent. Additionally, we report the Ti isotope compositions of 3421 Ma “sanukitoid-like” rocks from the Pilbara Craton, and of Paleozoic high Ba-Sr granite suites from the Northern Highlands Terrane, Scotland, which are proposed to be Phanerozoic sanukitoid analogues. These were measured using multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) at the Cardiff Earth Laboratory for Trace Element and Isotope Chemistry (CELTIC), Cardiff University. The Ti isotope compositions of these samples (file: 2024-004_Spencer-et-al_Ti-Isotope-Data.xlsx) are presented alongside a compilation of their previously published major and trace element concentrations (file: 2024-004_Spencer-et-al_Compiled-Isotope-Major-Trace-Element-Data.xlsx). Primitive (pre-Fe-Ti oxide saturation) samples have δ⁴⁹Ti values 0.1-0.2‰ heavier than modern arc basalts, the depleted mantle and the bulk silicate Earth. More evolved, post-oxide saturation samples show increasing δ⁴⁹Ti with SiO₂ content. These data are used to investigate the formation and differentiation of sanukitoid magmas.
