AbstractNTS 87-F/9 and NTS 87-F/10 are underlain by the upper Kilian Formation of the Neoproterozoic Shaler Supergroup and mafic sills of the Franklin event. Shallowly east- and northeast-dipping strata define the nose and southern flank of the Holman Island Syncline. Carbonate, shale, and evaporitic rocks of the Kilian Formation are poorly exposed beneath capping sills or as thin contact-metamorphosed septa between sills. West of a major lake named Ingilraniq, a thick sill forms a high plateau disrupted by many north-south and east-west trending normal faults. A lower sill occupies the floor of some valleys. East of Ingilraniq, four thick sills separated by sedimentary septa form a series of cuestas. Resistant sills form prominent west-facing cliffs and mesas, and extend towards the east as diabase-floored plateaux.
