Résumé(Résumé en langage clair et simple, non publié et disponible en anglais seulement)
Tectonic models provide regional geoscience knowledge frameworks for understanding distribution of rock units, associated mineral deposits and duration of mineral-prospective systems. This research builds on the GEM research in Yukon. We used compiled and new data to redefine the tectonic setting of plutonic and volcanic rocks that host intrusion-related deposits (Au-Cu-Mo) in Yukon. We identified that magmas were emplaced very rapidly and had distinct sources and characteristics. This is the first time that distinct magma sources have been identified. These data provide the basis for interpretation of mineral deposits and their distribution in the Cordillera as magma characteristics are paramount to understanding the mineralizing potential of intrusion related systems. The results of this research are applicable to understanding many intrusion-related systems in Canada.
