Bedrock Geology, Seagull Creek (105B/3), southern Yukon (1:50,000 scale)

Bedrock Geology, Seagull Creek (105B/3), southern Yukon (1:50,000 scale) The map area spans the western edge of the old North American continent and the terranes that accreted to it in Mesozoic time, which together form a generally west-dipping structural stack, separated by layer-parallel thrust faults. Three major elements are represented: 1) tilted strata of the ancient North American margin (Cassiar Terrane), 2) overthrust rocks that originated as volcanic arcs and off-shore sediments (Yukon-Tanana Terrane), and 3) granitic bodes injected into this thickened crust after the Cordilleran orogeny. 2024-07-30 Government of Yukon geology@gov.yk.ca Science and TechnologyYukon Geological SurveyYukon Data MapHTML https://data.geology.gov.yk.ca/reference/42254 Original metadata (https://open.yukon.ca)HTML https://open.yukon.ca/data/datasets/bedrock-geology-seagull-creek-105b3-southern-yukon-150000-scale
