International audience; The Luís Alves Terrane in southern Brazil is one of the largest expositions of the Archean to Paleoproterozoic units that acted as basement for the development of the Neoproterozoic Pan-African/Brasiliano orogenic belts in th

International audience; Recent studies have shown that a-damage in titanite influences He diffusivity and thus the closure temperature of the (U-Th)/He system in titanite. We compare different methods for measuring the alpha-dose in titanite by Raman
