Evidence of the Pampean cycle in the basament of the north-western sector of Sierra de San Luis

A preliminary zircon U-Pb age is presented for a feldspar-biotite gneiss from the Nogoli Metamorphic Complex, Sierra de San Luis, at San Francisco del Monte de Oro. The data show a cristallization age of 554 ± 4,8 Ma, which represents one of the first evidences of the Pampean Cycle in this geologica...
