Rb-Sr whole-rock isotopic study of late Archaean and early Proterozoic granitoid intrusions, Kainuu, Eastern Finland

A tonalite-granodiorite-granite suite emplaced during the late Archaean D, deformational phase yields a six point isochron age of 2,500 ± 270 Ma and an initial 87 Sr/ 86 Sr of 0.7044 ±0.0018.A rapakivi-type granite suite emplaced after the late Archaean episode and before the emplacement of early Pr...
