AbstractNTS 87-G/08 (Iglulik) straddles Minto Inlet. On the north shore, massive to bedded carbonates of the Boot Inlet and Jago Bay formations, quartz rich sandstone of the Fort Collinson Formation, and evaporites of the Minto Inlet Formation (Neoproterozoic Shaler Supergroup) host Type 1 and feldspar-porphyritic Type 2 sills. To the east, the Iglulik Peninsula is underlain by rocks of the Minto Inlet Formation and limestones and shales of the lower Wynniatt Formation. Minto Inlet strata host Type 1 sills. The southern shore of Minto Inlet is underlain by the upper carbonate members of the Wynniatt Formation into which were intruded Type 1 and 2 sills. A thin cap of Paleozoic clastic and carbonate rocks overlies an erosional unconformity on a hilltop. Toward the south, sparse exposures of Lower Kilian Formation carbonates and evaporites host Type 2 sills. All Proterozoic strata dip shallowly to the south, marking the transition from the Walker Bay Anticline to the Holman Island Syncline. North-northwest trending synmagmatic normal faults are exposed locally. East-northeast-trending post-Proterozoic normal faults locally show north-side down motions and repeat contacts.
