Despite the often divergent opinions regarding the evolution of the Teslin suture zone (TSZ), previous tectonic models broadly agree that the TSZ comprises a ductile shear zone that constitutes a fundamental crustal boundary (e.g., Tempelman-Kluit 1979; Erdmer 1985; Hansen 1989; Stevens and Erdmer 1996; Hansen and Dusel-Bacon 1998). In contrast, de Keijzer et al. (1999) offer a radical model in which the TSZ is a rootless polydeformed nappe obducted onto North America. According to their interpretation the TSZ does not represent a shear zone. Although the influx of new ideas in science is always commendable,...
