| Abstract | The northern flank of the Trans-Hudson Orogen on central Baffin Island comprises, from north to south 1) reworked Archean basement (Rae Province); 2) the Paleoproterozoic Piling Group, which comprises a
lower, pas- sive-margin sequence (Dewar Lakes and Flint Lake formations) and an upper, foredeep sequence (Astarte River and Longstaff Bluff formations); 3) a mafic volcanic thrust sheet (Bravo Lake formation); and 4) a metamor- phic-plutonic internal
zone. Field relationships suggest that the contact between the Piling Group and the underly- ing Archean basement is a reworked unconformity. Locally, the contact is obscured by the presence of large biotite syeno- to monzogranite plutons that
crosscut both the Piling Group and the Archean basement. Four distinct tectonometamorphic episodes are recorded, with an earlier, middle-amphibolite-facies Archean event (D 1A ), two compressional Paleoproterozoic events (D 1P and D 2P ), and a late
cross-folding event (D 3P ) that produced a set of basement culminations in the southern portion of the map area. |
