"NTS 87-G/7 is mostly underlain by Neoproterozoic rocks of the Shaler Supergroup, intruded by Franklin mafic and untramafic sills. Dolostone dominates the Boot Inlet and Jago Bay Formations, quartz-rich sandstone dominates the Fort Collinson Formation, whereas gypsum evaporites typify the Minto Inlet Formation. These gently south-dipping strata form the southern flank of the Walker Bay Anticline. North-northwest trending (syn-magmatic Proterozoic) and east-northeast trending (post-Proterozoic) normal faultsare ubiquitous, breaking up the outcrop pattern into polygonal blocks. Franklin intrusions belong to two magmatic series. Type 1 sills may have a peridotitic base and seem to have been preferentially emplaced just above the Fort Collinson sandstones. Thick Type 2 sills are commonly feldspar porphyritic, occur throughout the section, and form the crest of the Collingwood Hills. Dykes have planar to irregular contacts, some being localized along North-northwest trending faults. Paleozoic rocks outcrop in the westernmost part of the map area"--Abstract.
