| Abstract | The Wernecke Supergroup of Yukon is a metasedimentary succession deposited between ca. 1.66 and 1.60 Ga on the northwestern margin of ancestral North America (Laurentia). U-Pb detrital zircon geochronology, major and trace element geochemistry, and Nd isotope geochemistry reveal that the clastic sediments were derived mostly from collisional orogens that resulted from the amalgamation of Laurentia during Paleoproterozoic. Some detritus may have originated from non-North-American terranes such as eastern Australia or exotic arc terranes. Deposition of the Wernecke Supergroup occurred in a passive margin which resulted from the initial breakup of the supercontinent Columbia, and involved separation of northwestern Laurentia from adjacent continents, probably eastern Australia and the Yangtze craton of South China. This reconstruction is similar to the SWEAT configuration proposed for the Neoproterozoic supercontinent Rodinia. |
