Metadata Currency Date: January 2004 Business Theme: Geology CITATION Title: Geological Compilation of the Kirkland Lake Area, Abitibi Greenstone Belt (MRD 58 - Miscellaneous Release Data 58) Abstract: This map is the third, in a series of 1:100,000 maps to augment the former Timmins-Kirkland Lake Map 2205 (scale 1 inch to 4 miles). This geological map of the Kirkland Lake area was compiled from published maps and reports of the Ontario Geological Survey (OGS) and the Geological Survey of Canada (GSC). In addition, information from unpublished reports and maps on file with the OGS, university theses, papers in professional journals, geophysical maps and satellite images was incorporated. Geological interpretation was further enhanced by utilizing the Earth Resources and Land Information System (ERLIS) databases such as the Airborne Magnetic and Electromagnetic Surveys (AMEM - 1000 Series), Assessment File Resource Inventory (AFRI), the Drill Hole (DH) database, the Lithogeochemical (LGC) database and the Mineral Deposit Inventory (MDI) database, a (DEM) digital elevation model from the Ontario Ministry of Natural Resources. The map was produced as follows: geological compilation and interpretation by J.A. Ayer, and N.F. Trowell; compilation of mineral deposit data by J.A. Ayer, and N.F. Trowell ; preparation of base map by L. Valade; preparation of geophysical and satellite imagery by L. Valade and Z. Madon; GIS compilation of data by L. Valade and E. Amyotte. A vector mosaic, at a scale of 1:50,000, was digitally compiled using 1:20,000 scale Ontario Base Mapping Program - Digital Topographic Data Base (OBM - DTDB) map files. The resulting mosaic is based on the Universal Transverse Mercator (UTM) projection and grid system, Zone 17, North American Datum 1927. Purpose: This multi-year and multi-component compilation project will produce a series of 1:100,000 scale geological maps covering the Abitibi greenstone belt (AGB) in Ontario, in both hardcopy and digital formats. It will serve to identify areas for future mapping projects and will be used as a basis for tectono-stratigraphic interpretation of this mineral-rich area. The compilation products are designed to facilitate exploration for new deposits in areas of high economic potential by providing current geological data that incorporates the results of on-going research into the metallogeny and tectonic evolution of the AGB, and specific mineral-deposit-related issues. Time Coverage: Friday August 17, 2000 Time Coverage Comments: Date of publication. Area was last compiled by the Ontario Geological Survey (OGS) in 1973 with the publication of MAP 2205 - Timmins-Kirkland Lake Geological Compilation Series, Cochrane, Sudbury and Timiskaming Districts; 1 inch to 4 miles.

The digital files were then imported into ArcInfo v.7 and subsequently v. 8 (UNIX Solaris OS) to create the polygon topology. These files were then exported as ArcView 3.2 shape files as well as AutoCAD Map 4 drawing files in DWG and DXF formats (Windows NT OS). The airborne geophysics were processed in OASIS Montaj v. 4.3 to produce the various bitmap images. The DEM images was processed in PCI version 6.3 to produce the color shaded bitmap image, and processed in Arc/Info v. 8 to produce the greyscale bitmap image.
