Burwash Landing in Yukon is prospective for geothermal energy based on a high geothermal gradient, local occurrence of warm groundwater and proximity to the active, crustal-scale Denali fault. Uncertainties about the potential geothermal system include the nature and geometry of fluid pathways, and heat sources required to drive a hydrothermal system. In this study, we inverted three passive electromagnetic datasets\u2014321 extremely low frequency electromagnetic, 33 audiomagnetotelluric and 51 magnetotelluric stations\u2014to map the subsurface electrical structure to 8 km depth. Our new model reveals vertical conductive structures associated with the two main faults, Denali and Bock\u2019s Creek, which we interpret to represent fluid-deposited graphite and hydrothermal alteration, respectively. Our model supports an interpreted releasing bend on the main Denali fault strand. This is associated with the deepest conductivity anomaly along the fault and potential for deeper penetration of fluids. Enigmatic conductive bodies from 1 to &gt; 6 km depth are associated with intermediate to mafic intrusions. Fluids released from these bodies may advect heat and provide a possible heat source to mobilize hot fluids and sustain a geothermal system in the region.<\/jats:p>","DOI":"10.3390\/rs14235963","type":"journal-article","created":{"date-parts":[[2022,11,25]],"date-time":"2022-11-25T03:00:13Z","timestamp":1669345213000},"page":"5963","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Geothermal Exploration in the Burwash Landing Region, Canada, Using Three-Dimensional Inversion of Passive Electromagnetic Data"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2400-0550","authenticated-orcid":false,"given":"Victoria","family":"Tschirhart","sequence":"first","affiliation":[{"name":"Geological Survey of Canada Central Division, Natural Resources Canada, Ottawa, ON K1A 0E8, Canada"}]},{"given":"Maurice","family":"Colpron","sequence":"additional","affiliation":[{"name":"Yukon Geological Survey, Whitehorse, YT Y1A 0R3, Canada"}]},{"given":"James","family":"Craven","sequence":"additional","affiliation":[{"name":"Geological Survey of Canada Central Division, Natural Resources Canada, Ottawa, ON K1A 0E8, Canada"}]},{"given":"Fateme Hormozzade","family":"Ghalati","sequence":"additional","affiliation":[{"name":"Department of Earth Science, Carleton University, Ottawa, ON K1S 5B6, Canada"}]},{"given":"Randy J.","family":"Enkin","sequence":"additional","affiliation":[{"name":"Geological Survey of Canada Pacific, Natural Resources Canada, Sidney, BC V8L 4B2, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3910-4443","authenticated-orcid":false,"given":"Stephen E.","family":"Grasby","sequence":"additional","affiliation":[{"name":"Geological Survey of Canada Calgary, Natural Resources Canada, Calgary, AB T2L 2A7, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1007\/s11053-013-9199-3","article-title":"Geothermal Energy for Northern Canada: Is it Economical?","volume":"23","author":"Majorowicz","year":"2014","journal-title":"Nat.
