Abstract (Summary)

Paleozoic rocks in the northern Simpson Park Range, Tonkin Summit Quadrangle, are comprised of the syn-orogenic Roberts Mountains allochthon, the postorogenic Permian Garden Valley Formation, and autochthonous Devonian carbonates. Complex deformation includes the Late Devonian-Early Mississippian, Antler Orogeny, post-Antler thrusting, and Cenozoic Basin and Range extension. The Roberts Mountains thrust caused eastward advancement of deep marine, mainly siliciclastic strata on top of the shelfal, mainly carbonate platform during the Antler Orogeny. This study shows that an east-vergent, post-Antler thrust, emplace the topographically higher carbonate outliers of the autochthon on top of the Roberts Mountains allochthon. These carbonate masses sit on top of the Henderson thrust in the Tonkin Summit Quadrangle and timing of this thrust is constrained to be post-Permian.
