Abstract | NTS 87-H/6 is underlain by the middle to upper Wynniatt, Kilian, Kuujjua and Natkusiak formations of the Neoproterozoic Shaler Supergroup. The Wynniatt Formation is confined to the north-west and the
Kilian Formation is intermittently exposed in the central and southern parts of the map area. The upper Kilian, Kuujjua and basal Natkusiak formations are exposed on prominent hills in the southeast. Up to 5, type 2 (diabasic), sills outcrop as
stepped cuestas that strike northeast across the centre of the map area. Two, northwest-striking dykes cut across the upper Wynniatt Formation strata in the north. Several steep normal faults occur in the southern third and western side of the map
area. Those cutting the Natkusiak Formation do not cut underlying strata, suggesting that faulting was syn-volcanic. West-southwest block faulting, common in map areas to the north, is evident around Tahiryuak, where it repeats strata of the upper
Wynniatt Formation (unit n{W4). |
Summary | (Plain Language Summary, not published) NTS 87H/06 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 upper part of the Wynniatt Formation is well exposed along cuestas in the northern half of the map area. The lower half of the Kilian Formation is intermittently
exposed in the southern part of the sheet. The northern half of the area is affected by E-W block faulting, which preserves Cambrian sandstone and siltstone and a thick section of recrystallized Ordovician(?) dolostone (Victoria Island
Formation). |
