Phase 2 geoscientific preliminary assessment, lineament interpretation: township of Hornepayne and area, Ontario

This technical report documents the results of an updated surficial and geophysical lineament interpretation study conducted as part of the Phase 2 Geoscientific Preliminary Assessment to further assess the suitability of the Hornepayne area to safely host a deep geological repository. This study followed the successful completion of a Phase 1 Geoscientific Desktop Preliminary Assessment (Geofirma, 2013). The purpose of the Phase 2 lineament interpretation was to provide an updated interpretation of the geological and structural characteristics of the bedrock units within the area identified in the Phase 1 desktop assessment as warranting further studies, using high-resolution geophysical surveys and geological mapping. The assessment area considered for the lineament study includes the area covered by the newly acquired Phase 2 airborne surveys (SGL, 2017) and is divided into two blocks (Blocks A and B). The interpretation of lineaments was conducted using the new high-resolution airborne magnetic and digital elevation data (DEM), as well as high-resolution digital aerial imagery. (author)
