AbstractIn 2010, the Precambrian Geoscience Section (PGS), Ontario Geological Survey (OGS), started a multi-year regional compilation and bedrock geological mapping project in the McFaulds Lake region (Figure 12.1). This project, part of the core program of the Precambrian Geoscience Section, also represents an in-kind contribution to the Targeted Geoscience Initiative 4 (TGI-4), a multidisciplinary collaboration effort with the Geological Survey of Canada (GSC).
The main goals of this multi-year project are the following: 1) update the regional geological mapping in the McFaulds Lake region; 2) clarify and characterize the major lithologic units; 3) better understand the stratigraphy and age relationships between the various lithologies; 4) develop a better understanding of the actual extent of the mafic to ultramafic intrusions; 5) develop a better understanding of the structural and metamorphic history of the area; and 6) improve our understanding of the relationship of geophysical features to bedrock geology. Ultimately, this work will also lead to new insights on the overall understanding of the tectonic evolution of this poorly understood part of the northern Superior Province in Ontario.
The main purposes of this contribution are 1) to provide an update on the second year of field work; 2) to present some preliminary results based on new geological information acquired from re-logging and compiling diamond-drill holes, and also new geophysical data (Ontario Geological Survey - Geological Survey of Canada 2011 (released in August 2011); Rainsford et al., this volume); and 3) to provide an economic perspective on the McFaulds Lake region.
