| Abstract: | The southern Chilkat Peninsula is underlain by low-grade metamorphic rocks consisting of a thick unit of greenstone, in part of Carnian age, that is locally overlain by an attenuated section of calcareous sedimentary rocks and chert of latest Carnian to late Norian age and a thick flysch unit of Jurassic and/or Cretaceous age. The Triassic part of this sequence has previously been inferred to be part of the Taku terrane. However, its lithology, age, fossils, and regional distribution indicate that is is probably a sliver of Wrangellia that was offset from the eastern Alaska Range to its present position by at least 350 km dextral displacement on the Denali fault. -Authors |
