Ancient Pacific Margin NATMAP Project, year one

The Ancient Pacific Margin NATMAP Project, developed in response to demand from themineral industry, is a comprehensive analysis of the Cordillera-long belt of complexly deformed and meta-morphosedrocksofpericratoniccharacterknownprimarilyastheYukon-TananaandKootenayterranes.During the project’s first operational year, geological mapping began in the Wolf Lake–Jennings Riverarea on the British Columbia–Yukon Territory border and continued in the Vernon area of southern BritishColumbia. Detailed metallogenic studies were undertaken in both the Kootenay and Yukon–Tananaterranes. Bedrock and surficial geology reconnaissance studies in the Stewart River area provide the basisfor future work.The various components of the project will address the following: correlation between terranes;paleogeographic settings with emphasis on mineral-deposit modelling; timing and nature of tectonicevents; terrane mobility relative to the North American craton; the nature of tectonic boundaries. 1
