Sm-Nd and U-Pb systematics of single titanite grains
Combined Sm-Nd and U-Pb isotopic systems in single titanite grains from Archean rocks may be used to obtain Nd isotope composition at the time of titanite growth. The closed Sm-Nd system requirement is applied to titanite, and its integrity is monitored using the U-Pb system, in a similar way as U-Pb in zircon is used to interpret Lu-Hf data. The Nd isotope composition at the time of titanite formation can be used to infer initial Nd isotopic values of the rocks at the time of zircon...[Show more]
