Geological and geophysical data compilation for the western Wabigoon and southern Abitibi subprovinces of the Superior Province, Ontario, Canada

Geological layers representing geological observations (e.g., structural measurements, mineral occurrences) and interpretations (e.g., faults traces, map units) for and Archean greenstone belt near Dryden and Timmins, Ontario, Canada in the geological Superior Province. Newly interpreted layers such as lithology polygons (‘MapUnits’) and structural traces (‘Geolines’) are included as ESRI shapefiles.

Two geophysical datasets are provided, including a database of new magnetic susceptibility measurements from 2018 and 2019 field seasons near Dryden, Ontario. Additionally, an ensemble of reprocessed aeromagnetic grids (40 m by 40 m cell size) from the Ontario Geological Survey’s (2011) geophysical survey datasets are included as projected geo .tiff and .grd files. The ensemble includes total magnetic intensity with cosine roll off filtering, first vertical derivative, second vertical derivative, tilt derivative, and dynamic range compression. Hill-shaded relief grids are also included, and their azimuth and angle of incidence are indicated in their filename.
