Hafnium and silicon isotope evidence for multiple unsilicified basaltic sources at the origin of Rhyacian TTG magmas in the Mineiro Belt (Brazil)
Tonalite-trondhjemite-granodiorite (TTGs) are silica-rich plutonic rocks that correspond to the dominant lithologies of Archean basements. Understanding their formation is essential to unravel the early Earth tectonic regime and constrain continental crust formation and evolution. Archean TTGs commo
