The Cordilleran Ribbon Continent of North America

Annual Review of Earth and Planetary Sciences, 2008
The North American Cordilleran Orogen is the result of a two-stage process: (a) Triassic-Jurassic accretion within Panthalassa forming SAYBIA, a composite ribbon continent, and (b) Late Cretaceous collision of SAYBIA with North America. This model requires that a large portion of the continental foreland of the orogen is exotic. The exotic continental

Continent-scale linearity of kimberlite–carbonatite magmatism, mid-continent North America

Earth and Planetary Science Letters, 2014
Abstract Cretaceous–Tertiary kimberlite–carbonatite magmatism in mid-continent North America extends along a N40°W linear trend from Louisiana to Alberta, and occurs in at least four different pulses (∼109–85, 67–64, 55–52, and less than 50 Ma). The lack of spatial age progressions of magmatism consistent with motion of North America over a fixed hot
