AbstractThe 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.
Summary(Plain Language Summary, not published)
The Tectonic Map of Arctic Canada (TeMAC) is a compilation of all onshore and offshore tectonic units of Arctic Canada from the oldest Archean cratons to the youngest Neogene basins. TeMAC highlighs the deeper crustal features such as the nature and age of continental and oceanic crust, the age and distribution of ancient bedrock units and their evolutionary history spanning over 4 billion years of Earth history. TeMAC provides a synthesis of the complex tectonic history of the Arctic within an (international) seamless, internally-consistent and queriable framework. As a tectonic compilation and resource, it overcomes the existing limitations of legacy scientific interpretations and culture that are inherent to more local sources of data. It is expected to be of significant value to resource companies operating in Canada.
