Geology of the southern Campbell Range, southeastern Yukon: Implications for the tectonic evolution of Yukon-Tanana terrane

The southern Campbell Range in southeastern Yukon is underlain by rocks of Yukon-Tanana terrane, a Middle to Late Paleozoic volcanic arc terrane formed along and outboard of the margin of the western North American continental margin. The newly defined Klatsa metamorphic complex is a significant component of the southern Campbell Range and includes rocks that locally preserve the only evidence of Early Mississippian eclogite facies metamorphism within Yukon-Tanana terrane. Understanding the metamorphic and structural history of the region provides insight into the oldest subduction zone metamorphism in the terrane and the subsequent tectonic evolution of this part of the terrane.; Yukon-Tanana terrane in the southern Campbell Range consists of thrust-imbricated Upper Mississippian to Lower Permian metasedimentary rocks and Early Mississippian-metamorphosed Klatsa metamorphic complex.; Mississippian to Lower Permian prehnite-pumpellyite to greenschist facies metasedimentary rocks in the southern Campbell Range comprise three formations. Stratigraphically lowest White Lake formation chert and limestone are unconformably overlain by the King Arctic formation basal pebble to cobble conglomerate, lithic arenite and wacke. Money Creek formation carbonaceous phyllite, chert pebble conglomerate, and wacke unconformably overlie the two lower formations.* (Abstract shortened by UMI.); *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).
