摘要：
SHRIMP dating of Marine from metasyenites in the Central Zone of the Limpopo Belt yields a mean Pb-207/Pb-206 age of 2010 3 +/- 4 5 Ma calculated from 23 analyses This age combined with petrographic and field observations suggests the metamorphism in the syenites occurred during Palaeoproterozoic event (C) 2010 Elsevier Ltd All rights reserved
