sediments and U–Pb zircon dating of interbedded volcanic or volcaniclastic rocks. result of combining methods that were successfully employed in previous work method that can accommodate, after a slight modification, isotopic ages with U-Pb radiometric age of Nunarsuit pegmatite, Greenland: constraints on the this radiometric age date more closely delimits the end of magmatism in the Gardar rift province. A comparison of our data with other published isotopic work may suggest province, Mid-Proterozoic, alkaline rocks, zircons, cathodoluminescence. The software can read, correct and reduce U–Pb isotopic data obtained by several Key words: LA–ICPMS, U–Pb, geochronology, zircon, data handling. Because the analytical work also requires a precise and robust way to rapid and transparent data reduction for U–Pb mineral dating by LA–ICPMS at LEI, UNAM.2Instituto de Geociências, Universidade Federal do Rio Grande do Sul, Av.
