The Cape Smith Belt contains evidence for early Proterozoic plate tectonics in the form of a 1998 Ma ophiolite and a thrust belt which developed during northward under thrusting of a continental rift margin. Five tectonostratigraphic suites have been recognized from north to south in the eastern portion of the belt: (l) fluvio-deltaic sediments; (2) ca. 1960 Ma sediments and continental tholeiitic basalts; (3) ca. 1920 Ma transitional crust basalts; (4) deep-water sediments; and (5) basalts, sheeted dykes and mafic and ultra-mafic cumulates of a 1998 Ma ophiolite. Suites (1 ) to (3) reflect the development of a north-facing rift margin at the edge of the Superior Province. The older age of the ophiolite suggests that it developed in an earl...
