"The map area is underpinned by three Archean terranes from west to southeast: the Snow Island Suite of 2.6 Ga granite-rhyolite (AS), the Marjorie Hills assemblage of metasedimentary and granitoid gneiss (AMH), and orthogneiss of the Chesterfield block (unit Agn). The AS-AMH boundary is the Wharton Lake fault system, initially a southwest-dipping detachment. The AMH-Agn boundary is the dextral extensional Tulemalu Fault. Brittle reactivations of these faults localized sub-basins of the Baker Lake Group and hosted coeval intrusions of Martell Syenite (minette / about 1.83 Ga Hudson Granite mix). A Hudson Granite plug intrudes the AMH. Early gabbro/anorthosite (about 1.77 Ga) of the Kivalliq igneous suite was intruded by Nueltin granite, co-magmatic with bimodal Pitz Formation lavas and the about 1.75 Ga, 015° McRae Lake diabase dyke swarm and compositionally related 075° Thelon River dyke swarm. Cu-Pb veins and replacements formed near mafic centres and Au-Ag-bearing quartz veins near felsic centres"--Abstract.
