Exotic Terrane, complete video A geologic history of the Pacific Northwest that explains how islands near China accreted, or welded, themselves to the North American continent. Animations of the formation of North America explain the process. The video also visits Hells Canyon in Idaho.

1 Department of Geology, These two new lines of geologic data provide strong evidence confirming previous suggestions that Florida was part of Gondwana during the early Paleozoic and that its current configuration is that of an exotic terrane sutured to North America during the fragmentation of Pangea.

The Tchilit terrane in A¿r (Niger) is one of the most exotic terranes among those constituting the Tuareg shield. It is composed of low-K calc-alkaline metabasalts and meta-andesites (amphibolites), alkaline metarhyolites, detrital metasediments and of a syenogranite.

A geologic terrane is distinguished from neighboring terranes by its different history, either in its formation or in its subsequent deformation and/or metamorphism. Terranes are separated by faults. An exotic terrane is one that has been transported into its present setting from some distance.
