Geology, Ellef Ringnes Island south, Nunavut / [by] C.A. Evenchick and A.F. Embry.: M183-1/87-2012E-PDF

"Ellef Ringnes Island lies in the western Queen Elizabeth Islands, Nunavut, Canada (parts of NTS 69-C, -D, -E, -F, -G and 79-D, -E, -H). The bedrock consists mainly of Jurassic to latest Cretaceous sedimentary rocks of the Sverdrup Basin, and a thin veneer of Neogene sediments in the far north, adjacent to the Arctic Ocean. Strata are intruded by Cretaceous mafic sills and dykes, disrupted by several evaporite diapirs, and folded by northwest-trending folds associated with Eurekan (Paleogene) deformation. The majority of sills are concentrated close to the contact between Deer Bay and Isachsen formations (late Valanginian), but range as high as the lower Hassel Formation (late Albian). In the central and southern island, steeply dipping extensional faults occur in patterns radial to the evaporite domes. In the northern half of the island, steep faults and associated minor folds trend north-northeast, with the addition of east trending normal faults in the far north"--Abstract.
