Geology, Qiqittiivik, Victoria Island, Northwest Territories / [by] R.H. Rainbird ... [et al.].: M183-1/59-2011E-PDF
"NTS 87-H/5 is underlain by the upper Minto Inlet, Wynniatt and lower Kilian formations of the Shaler Supergroup. Together with diabase sills, the strata comprise the gently south-dipping northern limb of the Holman Island Syncline. The best exposures of the Wynniatt Formation (bedded-carbonate and shale) in the western Minto Inlier are located here. The lower half of the Kilian Formation (carbonate+evaporite) is intermittently exposed in the southern part of the sheet. Diabase sills are of diabasic type 2 (see legend). A dyke-like mafic intrusion occurs in the southwest part of the map area. The northern half of the area is affected by east-west block faulting, which preserves Cambrian sandstone and siltstone and a thick section of recrystallized Ordovician dolostone (Victoria Island Formation). An unconformity between the Wynniatt Formation and the Cambrian lower clastic unit reveals extensive paleokarst with paleo-caverns infilled with quartzarenite. The quartzarenite exhibits soft-sediment deformation, water-escape cylinders and other collapse features"--Abstract.
