Albitization at 1700 ± 2 Ma in the Sudbury – Wanapitei Lake area, Ontario: implications for deep-seated alkalic magmatism in the Southern province

Autor: M. P. Gorton, D. W. Davis, E. S. Schandl

Publikováno v: Canadian Journal of Earth Sciences. 31:597-607

U–Pb geochronology of hydrothermal monazite in albitized rocks from two gold deposits east of the Sudbury complex indicates that albitization in the Sudbury – Wanapitei Lake area occurred at 1700 ± 2 Ma and was coeval with a period of granitic p

U-Pb geochronology of igneous zircon from rhyolitic host rocks to the Archean Kidd Creek, Geco and Winston Lake massive sulfide deposits, in the Superior Province of Ontario, shows that volcanism, which accompanied mineralization, occupied a narrow t

Are the alteration halos of massive sulfide deposits syngenetic? Evidence from U-Pb dating of hydrothermal rutile at the Kidd volcanic center, Abitibi subprovince, Canada

Autor: E. S. Schandl, Donald W. Davis, Thomas E. Krogh

Publikováno v: Geology. 18:505

The Kidd volcanic complex is composed of felsic volcanic and subvolcanic rocks of Archean age. The felsic rocks are intercalated with sedimentary rocks, and are in contact with komatiitic ultramafic rocks. Large diorite plutons were emplaced into the
