Description: We report the titanium (Ti) stable isotope compositions (δ49Ti) of Neoarchean (ca. 2700-2650 Ma) tonalite-trondhjemite-granodiorite (TTG) suites from the Eastern Goldfields Superterrane, Yilgarn Craton. Samples were selected to cover the full range of trace element compositions exhibited by TTGs, and are primarily from the Kalgoorlie-Kambalda region of the Kalgoorlie Terrane. Ti stable isotope compositions 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: 2025-009_Spencer-et-al_Ti-Isotope-Data.xlsx) are presented alongside a compilation of their major and trace element concentrations (file: 2025-009_Spencer-et-al_Compiled-Isotope-Major-Trace-Element-Data.xlsx) taken from the Western Australian Geochemistry Database (WACHEM). Most TTG samples have δ49Ti values between 0.2 to 0.6‰ that increase with SiO2 content, while two highly evolved TTGs have δ49Ti > 1‰. At SiO2 ≈ 70 wt% the different TTG geochemical groups display distinct Ti isotope compositions.
