1 day Oral and Poster

Sponsored by Structural Geology & Tectonics Division

Steady progress is being made in the understanding of Laurentia, the Precambrian basement of the North American craton: from the origin and evolution of individual Archean cratons, and the Proterozoic collisions that brought them together, to the paleogeography of supercontinent Nuna, the younger Proterozoic cover sequences that blanketed part of this first modern supercontinent, and finally the rifting and break-up of Laurentia, as part of Rodinia, in the late Proterozoic. This session will highlight some of the latest progress from a variety of fields, with an emphasis on northern Laurentia and the Arctic.
