Abstract

Two major magmatic pulses of the granitic Florianopolis Batholith in Santa Catarina State. southern Brazil, occurred between 613 +/- 5 Ma and 595 +/- 5 Ma, during the Neoproterozoic Brasiliano Cycle. These ages were obtained by U-Pb isotopic determinations with the sensitive high mass-resolution ion microprobe on igneous zircons from Pedras Grandes Suite in Santa Catarina State. Euhedral zircons remained unaltered close to a fluorite vein deposited at 180degreesC or more. These ages suggest a northern limit for the Pedras Grandes; Suite, explaining the spatial relationship between the fluorite veins and the source rock.
