SHRIMP U-Pb zircon dating of Neoproterozoic granites from the easternmost São Roque Domain, Ribeira Belt
Four granitic plutons from the easternmost portion of the São Roque Domain (SRD) were dated by U-Pb zircon SHRIMP; the results indicate that the peak of granitic magmatism was concentrated in a short interval (606–589 Ma), the same as in the central portion of the SRD. The two porphyritic biotite g...
