Description: The database was developed by interpretation of satellite and aeromagnetic data in conjunction with bedrock maps, from both proprietary and non-proprietary sources, and has allowed generation of new data and reinterpretation of geological relationships. Rock units are classified into a harmonized legend with pan-Slave applicability. Point data including kimberlite locations and geochronological sample sites form an integral component of the database. The traces of numerous interpreted and mapped faults, diabase dykes, and topographical lineaments contribute to significant advancements in the understanding of the Slave’s crustal fracture systems.
This compilation builds upon a similar product released by the Northwest Territories Geological Survey (formerly the Northwest Territories Geoscience Office) in 2005 as NWT-NU Open File 2005-01. Upgrade, revision, and expansion of geological information primarily by M. Stubley; database design and integrity, and topological consistency by D. Irwin. Both the Northwest Territories Geological Survey and the Canada-Nunavut Geoscience Office, the latter through NRCan, provided financial support to M. Stubley.
The compilation was created using ArcMap 10.6.1, and is amenable to integration to other GIS platforms. All data was originally projected to Universal Transverse Mercator (UTM) Zone 12 North using North American Datum 1983 (NAD83). The accuracy of geological relationships reflects the source data. Many areas are valid at scales of 1:30,000 to 1:50,000, but more-detailed source data are simplified prior to incorporation.
