Lithogeochemistry, geochronology and geodynamic setting of the Lupa Terrane, Tanzania: Implications for the extent of the Archean Tanzanian Craton

Herein we provide new zircon U–Pb ID-TIMS, U–Pb LA-MC-ICP-MS and Lu–Hf LA-MC-ICP-MS results from the Lupa Terrane, SW Tanzania, and demonstrate that previously considered Paleoproterozoic granites comprising the Paleoproterozoic Ubendian Belt are in fact Archean (ca. 2.74 Ga). Disparately older inherited zircons (ca. 2.85 Ga) and Lu–Hf zircon model ages (≥3.1 Ga) suggest that these Archean granites likely interacted with substantially older...
