AbstractNTS 87-F/15 is underlain by the Kilian and Kuujjua formations of the Neoproterozoic Shaler Supergroup. The shallowly dipping strata define the nose and northern flank of the Holman Island Syncline. Carbonate, shale, and evaporitic rocks of the Kilian Formation are well exposed as cliff sections beneath capping sills, but also form a plateau in the west-central part of the map area, where a small, circular, gabbroic body is interpreted to be a laccolithic offshoot of an unexposed sill. The sharp, conformable contact between the Kilian Formation and overlying-Kuujjua Formation is exposed in the eastern part of the map area. Up to 6 Type 2 (diabasic) sills outcrop as stepped cuestas that strike north to northeast across the entire map area. Some of the sills appear to branch towards the southwest. Some sills appear to cut across the sedimentary strata at a shallow angle. Several steep, northeast and north striking lineaments (possible normal faults) occur in the western part of the map area.
