    The Borrachudos Granitic Suite: Paleo- to Mesoproterozoic A-type Magmatism in the Southeastern São Francisco Craton (SE Brazil) by IVO ANTONIO DUSSIN, MARIO LUIZ S.C. CHAVES, TANIA MARA DUSSIN, PHILLIPPE ROSSI, JACQUES CHARVET

    Published 2025-01-01
    “…Previous papers attributed the magma genesis to crustal thickening related to an older Paleoproterozoic, Transamazonian orogeny. However, geochronological data indicate that BGS is younger, dominated by about 1.7 Ga granitoids hosted in the archean basement. …”
