~990 Ma peak granulitic metamorphism and amalgamation of Oaxaquia, Mexico: UPb zircon geochronological and common Pb isotopic data
The ~1 Ga Oaxacan Complex is the largest exposure of the Oaxaquia terrane of Mexico. Microprobeanalysis of co-existing ortho- and clino-pyroxene, garnet, ilmenite and plagioclase indicate metamorphicconditions of 735 ± 5° C and 7.7 ± 0.1 kbar in the granulite facies, which was dated between ~998 and...
