AbstractA 3D geologic model of the Flin Flon exploration camp has been compiled from integrated analyses of drill core, 2D and 3D seismic, mine survey and geological map data. The 3D model is built from a series of lithostratigraphic and fault surfaces which are, together with their underpinning drill hole and map constraints, represented in a '3D knowledge cube'. The geometry and attitude of the 3D lithostratigraphic surfaces, and their topological relationships with multiple generations of shear zones and thrust faults, suggest that the Flin Flon exploration camp is underlain by an E-dipping stack of W-vergent thrust imbricates formed by post- and possibly pre-Missi deformation events. The imbricate stack was subsequently deformed by trending ductile thrust faults that internally imbricated the Flin Flon arc assemblage and Missi sedimentary rocks and brought up rocks of the former against the latter in a northerly direction. The VMS-hosting Millrock member has been stacked on at least four structural levels, enhancing the VMS potential in the footwall and hanging wall vicinities of the known ore deposits where both thrust systems intersect. N-trending post-metamorphic subvertical faults have further segmented the polyphase imbricate stack, complicating the correlation of lithostratigraphic successions across them.
