PHASE 2 GEOSCIENTIFIC PRELIMINARY ASSESSMENT GEOLOGICAL MAPPING, TOWNSHIP OF IGNACE AND AREA, ONTARIO

These include, one area in the northern portion of the Revell batholith, one area in the southeastern portion of the Basket Lake batholith, one area in the adjacent western portion of the Indian Lake batholith, and one area in the eastern portion of the Indian Lake batholith (Figure 1.2). [...] However, sensitivity analyses that decreased the density of the bedrock unit underlying the batholith suggests that the western portion of the batholith could thin to approximately 0.5 kilometres, and to 0.8 kilometres north of the candidate area in the eastern part of the batholith. [...] The Kenora-Fort Frances dykes form clusters in the Melgund Lake area to the northwest of the Revell batholith, and in the Mameigwess Lake area between the Basket and Indian Lake batholiths. [...] The purpose of the scanline fracture mapping exercise is to assess both the nature and extent (if any) of the damage to the bedrock caused by dyke emplacement and the nature and extent of brittle deformation overprinting the dykes themselves. [...] The table of contents for the report was specified by the NWMO and developed prior to the completion of the mapping stage of the Phase 2 Detailed Geological Mapping activity.
