The Geo-mapping Frontiers project was initiated to improve geoscience knowledge in the least understood parts of Canada's north. This publication presents a compilation and interpretation of geologic structures derived from both high and low resolution enhanced magnetic data (available from the GSC), enhanced LANDSAT imagery and topographic (DEM) data. The data sets included in this OPEN FILE include low resolution airborne magnetic data, a CDED DEM, legacy geological data (IPY map) and structural data compiled by the Yukon and NWT Geological Surveys as well as a newly interpreted dataset of geologic structures for the entire area of Canada's Arctic north of 60°. This is the second of a series of reports for the Geo-mapping Frontiers project, and is intended to provide structural information for mapping and exploration in Canada's Arctic.
