| Abstract | Victoria Island is in the western Canadian Arctic Islands, Northwest Territories, Canada (parts of NTS 87-G, 87-H, 88-A and 88-B). The bedrock consists of Cambrian to Devonian sedimentary rocks
(sandstone, limestone and dolostone) that unconformably overlie Neoproterozoic rocks. Eight map units are recognized and mapped. Strata are generally flat lying or have a very gentle northwest dip. Numerous ENE-WSW oriented normal faults offset lower
Paleozoic strata and locally increase the dip. At least some of these faults were active in the Early Cambrian and again in the Middle Cambrian. The faults cut a Devonian unit indicating fault movement after that time. An anomalous circular structure
in the northeastern part of the map area, approximately 25 km in diameter, contains steep dips, faulting and numerous shatter cones. It is interpreted as the root of a meteorite impact crater. |
| Summary | (Plain Language Summary, not published)
This map shows the distribution of rocks on northwestern Victoria Island, Northwest Territories. The rocks are between about 520 million years old and
390 million years old. They consist of sedimentary rocks including sandstone, shale, limestone and dolostone. Eight formations are recognized and mapped. Strata are generally flat lying or have a very gentle northwest dip. Numerous faults cut the
rocks. The 25 km diameter Tunnunik meteorite crater is exposed in the north-central part of the map area. |
