AbstractThe principal structural components of Meta Incognita Peninsula, south Baffin Island, include a widespread penetrative foliation, four arrays of kinematically linked thrusts, and southwest-vergent folds up to tens of kilometres in wavelength. These structures collectively comprise the southwest-vergent Meta Incognita thrust belt. The thrusts are intruded and structurally overlain to the northeast by the Cumberland Batholith. The generalized structural sequence starts with formation of a low-angle foliation, followed by regional thrusting, folding, and localized strike-slip shearing. All preserved deformation structures formed at granulite facies. The Meta Incognita thrust belt is interpreted as the high temperature equivalent of the Cape Smith thrust belt, Ungava Orogen, northern Quebec.
