"NTS 87-G/1 is underlain by shallowly dipping sedimentary rocks of the upper Wynniatt, Kilian, and Kuujjua formations of the Neoproterozoic Shaler Supergroup, intercalated Franklin sills, and by basaltic lavas of the Natkusiak Formation, which define the northern flank of the Holman Island Syncline. Carbonate rocks of the upper Wynniatt Formation are well exposed near the coast of Minto Inlet, where they are cut by two thick diabase sills, and by prominent east-northeast striking normal faults. Carbonate, shale, and evaporitic rocks of the Kilian Formation are exposed beneath thick cappingsills that form a series of cuestas. A northwest-trending fault zone near the eastern edge of the map truncates sills and guided ascent of basaltic dykes, some of which have meter-scale semi-massive sulfides concentrated at their contacts. Rocks of the Upper Kilian and Kuujjua formations are well exposed in a cliff near the southern edge of the map area. The cliff top and plateau to the south expose basal and sheet flow units of the Natkusiak Formation"--Abstract.
