Pearya terrane lies on northernmost Ellesmere Island and has been interpreted as exotic to North America, prior to Silurian juxtaposition at approximately 430 Ma. This hypothesis was tested through detrital zircon analysis that showed a gradational change in provenance between the Pearya terrane and well-defined North American rocks, which is more consistent with a connection in the Cambrian, rather than a large separation. Thomas Hadlari of the Geological Survey of Canada and colleagues propose a return to an older tectonic model of the Pearya terrane wherein convergence recorded by the M'Clintock orogeny began along the Franklinian margin of North America in the mid-Ordovician, at approximately 475 Ma.
