Geochronological constraints on metamorphism, magmatism and exhumation of deep-crustal rocks of the Kramanituar Complex, with implications for the Paleoproterozoic evolution of the Archean western Churchill Province, Canada

Geochronological constraints on metamorphism, magmatism and exhumation of deep-crustal rocks of the Kramanituar Complex, with implications for the Paleoproterozoic evolution of the Archean western Churchill Province, Canada

U-Pb and Sm-Nd geochronology establishes an important Paleoproterozoic (~1.9 Ga) history for the Kramanituar Complex, located in the interior of the Archean western Churchill Province, and provides further insight into the Snowbird tectonic zone, a crustal-scale (> 2000 km) feature whose role dur...

Zusammenfassung:U-Pb and Sm-Nd geochronology establishes an important Paleoproterozoic (~1.9 Ga) history for the Kramanituar Complex, located in the interior of the Archean western Churchill Province, and provides further insight into the Snowbird tectonic zone, a crustal-scale (> 2000 km) feature whose role during Precambrian time remains controversial.
