Degree: Master of Science Abstract: 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...
