AbstractThe Archean and Paleoproterozoic rocks of western central Baffin Island are being mapped at 1:100 000 scale at the exposed topographic surface. This data is being used to create three-dimensional (3D) structural models of key lithotectonic boundaries and associated deformation fabrics. Initial field investigations indicate extensive base- ment involvement during Paleoproterozoic deformation, along with folding and thrusting of cover rocks. Three-dimensional modelling of the complex structures produced by these processes would help extend our geo- logical interpretations, now confined to 2D models in the form of geological maps, into the subsurface, thus helping to constrain the tectonic framework in this northern margin of the Trans-Hudson Orogen. Three-dimensional mod- elling activity is focused on extending the geometry of the basement (Archean) / cover (Paleoproterozoic) bound- ary, vergence mapping of regional folds and faults developed in the upper sequence of the Piling Group (Longstaff Bluff Formation), and the high-resolution 3D mapping of the base of the mafic volcanic Bravo Lake Formation.
