... 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...

... Canada 2001 We reply to the criticisms of Oliver and Hansen on our paper on the structure and tectonic significance of what we prefer to call the Teslin zone (TZ) and Oliver and Hansen the Teslin suture zone (TSZ). They criticize %(% i ) our “scientific methodology,” ( ii ) our interpretation...

...Martin de Keijzer; Paul F Williams; Richard L Brown Abstract The Teslin zone in south-central Yukon has previously been described as a discrete zone with a steep foliation unique to the zone. It includes the Anvil assemblage and the narrowest portion of the Yukon-Tanana terrane (the Nisutlin...

...Robert A. Creaser; Larry M. Heaman; Philippe Erdmer Abstract Zircon from eclogite near Last Peak in the Teslin tectonic zone yielded a U–Pb isotopic age of 269 + 2 Ma (2σ), the first precise age for such a rock in the Yukon –Tanana terrane of the Canadian Cordillera. Both the morphology...

...R. A. Stevens; P. Erdmer; R. A. Creaser; S. L. Grant Abstract Metamorphosed and ductilely deformed sedimentary, plutonic, and volcanic rocks of the Nisutlin and Anvil assemblages make up the Yukon–Tanana terrane in the Teslin tectonic zone study area. The Nisutlin assemblage consists of siliceous...

...Vicki L. Hansen; James K. Mortensen; Richard L. Armstrong Abstract The Teslin suture zone (TSZ) comprises a portion of the Yukon–Tanana terrane (YT), in the Yukon, formed by steeply dipping layering and L–S tectonite foliation. The TSZ forms the fundamental tectonic boundary between rocks deposited...

... that the zone thins in the mid-crust and widens near the Moho. This apparent variable width versus depth of the Tintina fault is atypical of major strike-slip faults worldwide. The Teslin fault was an active terrane boundary during accretion of terranes onto North America. Observed reflection geometries...

... prior to 425 km of post-Late Cretaceous dextral displacement along Tintina fault (Tintina). CR, Campbell Range; CT, Cassiar terrane; JCF, Jules Creek fault; KS, Klondike schist; SA, Sylvester allochthon; SCK, St. Cyr klippe; TFZ, Tummel fault zone; TZ, Teslin zone. Blueschist and eclogite occurrences...

...Vicki L. Hansen Abstract Lineated and foliated tectonites of the Teslin suture zone, Yukon, represent the deep-seated part of a west-dipping subduction complex that formed seaward of western North America in Permian-Triassic time. The tectonites were progressively underplated onto the hanging wall...

... the eastern margin of the Intermontane Belt by as much as 300 km. These faults, including the Kutcho and the Pinchi, connect in part with the Teslin Suture Zone in Yukon Territory and probably with the Fraser River-Straight Creek fault zone in southern British Columbia. Although dextral transcurrent faulting...

...; ϵNd T , 4.2 to 1.4), non-subduction-related source identified as the host Cache Creek terrane; and an isotopically slightly more evolved (Sr i , 0.7094 to 0.7101; ϵNd T , 4.5 to –7.3), subduction-related source identified as the host Stikine terrane. Immediately east of the Teslin Tectonic Zone (TTZ...

... largely retrograded by postsubduction metamorphism. Their existence is interpreted as additional evidence of the link between nappes above the Cassiar terrane and their inferred root, the Teslin suture zone. The Nisutlin and Anvil allochthonous assemblages can now be interpreted, not simply as crustally...

... Columbia; it lies west of the Tintina – Northern Rocky Mountain Trench fault and Teslin Suture Zone and east of the Denali – Shakwak fault. Volcanic sections were sampled in three regions spread over 300 km, providing the first paleomagnetic data from pre-Tertiary volcanic rocks in the northern Canadian...
