Abstract

Recently obtained paleomagnetic, geochronologic, and seismic data are greatly improving our understanding of the tectonics of northeastern Russia, which lies in an accretionary zone between the stable platforms of the North American and Eurasian plates. In particular, the present-day plate boundaries and motions have been clarified and a model has been developed for the accretionary history of the poorly understood Mesozoic fold belts of northeastern Russia. The evolution of northeastern Russia appears to be similar to that of Alaska and the Canadian Cordillera, and many similar tectonic and stratigraphic features can be identified in all three regions.
