“…Neoproterozoic granite magmatism was widespread in Socorro-Guaxupé Nappe System in Eastern São Paulo state and neighboring areas (e.g., Campos Neto et al 1984, Wernick et al 1984, Artur et al 1991, Haddad 1995, Campos Neto & Caby 1999, Vinagre et al 2014. The most voluminous occurrences are made up of, compositionally expanded, high-K calc-alkaline syn-orogenic granites (lato sensu), which build the Socorro and Ipuiúna batholiths (e.g., Campos Neto et al 1984, Wernick et al 1984, Haddad 1995, Haddad et al 1997.…”

“…The oldest magmatic rocks recorded in the Socorro batholith are foliated charnockites rocks that show transitional contact to texturally similar orthogneisses (Wernick et al, 1984b). The age of the Socorro charnockite (~642 Ma) overlaps those of regional orthogneisses (in part also of charnockitic character) considered as associated with pre-collisional tectonics (subduction-related?…”

“…The older reliably Neoproterozoic plutonic rocks present in the area are gneissified charnockites with high-K calcalkaline affinities dated at 660 Ma by both Rb-Sr and U-Pb methods (Figueiredo & Campos Neto 1994, Basei et al 1995. The huge Pinhal-Ipuiuna (Haddad 1995) and Socorro (Wernick et al 1984) batholiths are made up of chemically expanded suites with typical high-K calc-alkaline signatures; the latter was recently dated at 629 ±10 Ma by U-Pb zircon geochronology (Topfner 1996).…”
