Geochronological and geochemical constraints on the origin of the Paleoproterozoic Union Island Group mafic magmatism, East Arm Basin, N.W.T.
DownloadFall 2017
The Slave craton underwent widespread extension during the Paleoproterozoic. In the southern Slave craton, this extension is manifest in multiple periods of continental mafic magmatism emplaced between 2.3–2.2 Ga and prior to 2.0–1.9 Ga calc-alkaline magmatism of the Taltson and Thelon zones...
