Chronological study of the pre-Permian basement rocks of southern Patagonia

Small outcrops of the basement of the Deseado Massif, consisting of weathered, altered granitoids and their metasedimentary host rocks, were dated by the U-Pb zircon method using thermal ionization mass spectrometry and ion microprobe (SHRIMP). The provenance ages of detrital zircon in the metasedim...
