The Yukon-Tanana Terrane is a geologic terrane in the Canadian Yukon and eastern Alaska, consisting of metamorphic and igneous rocks that have been accreted onto the North American continent. This terrane is significant in tectonics and regional geology for understanding the processes of terrane accretion, the tectonic history of the Cordilleran orogen, and the mineral resources in the region.
