SHRIMP dating of titanite from metasyenites in the Central Zone of the Limpopo Belt, South Africa [查看] M.J.Rigby、R.A.Armstrong

SHRIMP dating of titanite from metasyenites in the Central Zone of the Limpopo Belt yields a mean 207Pb/206Pb 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.
