"NTS 87-G/9 (Nalluryaq) and the southernmost part of NTS 87-G/16 are mostly underlain by Neoproterozoic Shaler Supergroup sedimentary rocks, with limestone and dolostone of the Boot Inlet and Jago Bay formations, quartz arenite of the Fort Collinson Formation, and gypsum evaporite of the Minto Inlet Formation. The latter locally form quarryable alabaster deposits as a result of contact metamorphism. Sedimentary rocks are injected by basaltic sills and dykes of Franklin age (ca. 720 Ma) that can be divided into older, more olivine-rich Type 1 intrusions and younger diabasic to feldspar-porphyritic Type 2 intrusions. Fe-oxide exoskarns are developed in the hangingwall panels of some synmagmatic normal faults. Strata are either flat-lying, or dip gently to the north or south to either side of the Walker Bay Anticline. Steeper bedding orientations occur near faults as a result of structural entrainment. A regional-scale basal unconformity separates Paleozoic clastic and carbonate rocks in the north from underlying Proterozoic rocks to the south, but the contact is often faulted, and isolated domains of Paleozoic rocks are preserved within graben. North-northwest-trending syn-magmatic (Proterozoic) and east-northeast-trending (Phanerozoic) normal faults are ubiquitous, breaking up the outcrop pattern into a series of polygonal blocks"--Abstract.
