Abstract | NTS 87-H/3 is underlain by the middle to upper Kilian, Kuujjua and Natkusiak formations of the Neoproterozoic Shaler Supergroup. Together with ~3 diabase sills (type 2), spaced at regular intervals
within the host sedimentary rocks, the strata comprise the gently south-dipping northern limb of the Holman Island Syncline. The northwest of the map area is dominated by a thick sill, which forms a prominent SE dip slope down to the Kuujjua River.
Sedimentary strata are best exposed along a prominent cuesta that faces north-northwest along the south side of the Kuujjua River. The upper Kilian Formation and crossbedded quartzarenite of the disconformably overlying Kuujjua Formation are
prominent along the cuesta's face together with conformably capping basalt flows of the Natkusiak Formation. Of note in this area, are quartz-arenite layers in basal lava flows of the Natkusiak, indicating that rivers which formed the Kuujjua
sandstones continued to deposit detritus during volcanism. |
Summary | (Plain Language Summary, not published) Bedrock Geology of NTS 87H/03, western Minto Inlier of Victoria Island. The area is underlain by sedimentary and volcanic rocks of the early
Neoproterozoic Shaler Supergroup. |
