Miscellaneous Release—Data 317
Chatham Sag Aeromagnetic Lineament Study; by Ontario Geological Survey. This release contains a lineament analysis of aeromagnetic data in the Chatham area of southwestern Ontario. In 2009, the Ontario Geological Survey conducted an aeromagnetic survey (Geophysical Data Set 1065) over the Chatham Sag, which is a depression on the ridge between the Michigan and Appalachian basins. It is within this depression that the thickest Paleozoic strata in southern Ontario have accumulated. Important regional faults (Dawn, Electric) have previously been identified in the study area. In 2013, a lineament analysis of the aeromagnetic survey was contracted to TerraNotes Ltd. The structures identified through the analysis by TerraNotes Ltd. were recognized solely based on the aeromagnetic survey and, therefore, were determined to be associated with the Grenvillian basement. The products found in this release were all generated by TerraNotes Limited. This release includes a report in portable document format (.pdf); 21 grids in Geosoft® binary GDB format (.grd, .grd.gi files); 140 images (4 .tif and 136 .png files); 25 shapefiles (.cpg, .dbf, .prj, .sbn, .sbx, .shp, .shx files); and 4 structural indices (comma-delimited ASCII (.csv) files) used in the Euler deconvolution of the magnetic data to obtain apparent depths to magnetic sources. The projection for all grids and shapefiles is in Universal Transverse Mercator (UTM) Zone 17 using North American Datum 1983 (NAD83). The study and associated files are provided on 1 DVD. $25.00.
