Tectonic map of Arctic Canada

The Tectonic map of Arctic Canada (TeMAC) presents a tectonic synopsis of all onshore and offshore areas north of latitude 60°N at a scale of 1:4 000 000. Data sources include territorial and national compilations locally incorporating field work up to 2010 at scales of 1:100 000 to 1:5 000 000 and new compilation work for parts of Nunavut and Northwest Territories. One hundred and two tectonic domains are documented and include: 5 cratons, 37 basins, 2 platforms, 3 shelves, 2 plains, 1 ridge, 3 oceanic domains, 7 cover sequences, 15 accreted terranes, 16 magmatic suites, and 11 orogens. Stripe patterns are utilized to indicate the extent of orogenic overprinting with stripe colour keyed to individual orogens. Applications of TeMAC include 1) providing a new tectonic compilation and database context for Arctic Canada; 2) encouraging frontier mineral and energy exploration; and 3) providing general support for the geological framework developed for the delineation of the outer limits of Canada’s Arctic continental shelf.
