The domain also hosts the only producing gold mine in Saskatchewan, Seabee Gold Operation, currently producing from the Santoy deposits situated along a splay of the Tabbernor fault zone. This thesis presents results of structural study at a range of scales and involves two main components: a broad-scale analysis of the structural geology of the central Glennie Domain, coupled with detailed mapping and 3D modelling of the Gap Hanging Wall deposit in the Seabee area of the eastern Glennie. The regional-scale analysis covered three distinct map areas collectively spanning a 60 by 45 km area of the central Glennie Domain. Each area was separated into sub-cylindrical, uniform structural domains to isolate individual fold interference patterns and quantify the geometry of related folds. These techniques established that F3 are NNW-trending, open and inclined to upright in Areas 1 and 3, whereas they are similarly trending but close to tight in Area 2. Average F3 attitudes are – Area 1: axial plane (AP) 160°/82° (hinge line (HL) steep, doubly-plunging); Area 2: AP 346°/79°, HL 55° → 002°; Area 3: AP 347°/72°, HL 65° →124°. F4 was quantified in Areas 1 and 3 as SW-trending, open and moderately-steeply inclined with a gently-moderately NE-plunging fold axis. Average F4 attitudes are – Area 1: AP 232°/67°, HL 25° → 042°; Area 3: AP 249°/61°, HL 35° → 046°. F4 could not be quantified in Area 2 due to the overwhelming influence of D3 Tabbernor-related structures. To complement this analysis, and to explore areas with less robust datasets (Area 3), remote predictive mapping and remote sensing techniques were employed, namely lineament analysis of the Shuttle Radar Topography Mission image and magnetic susceptibility maps. The lineaments tend to align most prominently with the axial plane of the latest pervasive folding event in the area, while also highlighting previous folding event(s), and subsequent brittle events. The local-scale analysis involved structural study and 3D modelling of the Gap Hanging Wall deposit, hosted in an apophysis of the tonalitic Lizard Lake pluton (LLP), to establish controls on gold mineralization. Mapping revealed that the apophysis contains several N-plunging folds, reflecting D3 shortening in the limb of a regional s-fold in the western limb of the Carruthers Lake synform. Gold is associated with two stages of quartz veins; vein set 1 is expressed as a healed fracture network inferred to have been emplaced in fractures during D3 shortening, and vein set 2 was emplaced during continued shortening, axial planar to deposit-scale F3 folds. This probably resulted from the build-up of fluid pressure that exploited the axial planar cleavage; alternatively, vein set 2 may have originated as extension fractures along outer arc of fold that were later rotated and flattened. Both stages of veins are restricted to the plutonic host rock and associated with a distinctive cream to pistachio green alteration. 3D modelling included an initial cubic model built in Leapfrog GeoTM using lithologs to identify hanging wall and footwall contacts of the LLP, together with a detailed model that focused on the character of the deposit at depth. By adding Au assay results, a numeric model was created which shows that the gold anomalies tend to be concentrated along the Syn-2 (an F3 synform) trough of the deposit-scale folds. Accordingly, gold-bearing fluids are inferred to have migrated from depth and infiltrated fold hinge zones, where dilational space had been created during microfracturing in the early stages of shortening and incipient folding.","abstract_html":"The Glennie Domain of northern Saskatchewan, centrally located within the Reindeer zone of the 1.9-1.8 Ga Tans-Hudson orogen, is a poly-deformed terrane with evidence of at least four phases of ductile deformation and resultant complex fold interference patterns.
