Precambrian Geoscience
Miscellaneous Release—Data 261
Geochemistry of Midcontinent Rift-Related Mafic Intrusions, Thunder Bay Area; by M.C. Smyk and P. Hollings. This release is part of an ongoing project to examine and characterize the mafic sills and dikes that extend from south of Thunder Bay to northeast of Lake Nipigon, representing the northern expression of the Mesoproterozoic Midcontinent Rift. This data release includes geochemical analyses for 267 bedrock and diamond-drill core samples collected from a variety of intrusions on the Black Bay and Sibley peninsulas and around the city of Thunder Bay between 1999 and 2008. In addition, a representative subset of 34 samples was analyzed for Rb-Sr and Sm-Nd isotopes in order to subdivide the mafic intrusions near Thunder Bay and to allow comparison with sills identified around Lake Nipigon. The data, a brief project summary and a map of sample locations are available as Microsoft® Excel®2003 (.xls), Microsoft®Word® 2003 (.doc) and portable document format (.pdf) files on 1 CD. $20.00.

Miscellaneous Release—Data 263
Surficial Geology Map Compilation of the Abitibi Region, Northern Ontario; by Ontario Geological Survey. The Ontario Geological Survey (OGS), Sedimentary Geoscience Section, has generated an attributed GIS-based, seamless surficial geology compilation map of the Abitibi region, northern Ontario. A total of 26, 1:50 000 scale surficial geology maps published by the OGS were used in this compilation. Map data are provided as ESRI ArcInfo® coverages in UTM zone 17 NAD 83 and completed .mxd project files. The map data set captures information on Quaternary geological units; sand and gravel pits; linear features, such as eskers and bluffs; and point features, such as drumlins and glacial striae. Also included is a shaded relief image of the area, created using the digital elevation model (DEM) produced by the Ontario Ministry of Natural Resources. The data are also provided in .kml format for viewing in Google™ Earth. A “readme file” is included in Microsoft® Word® (.doc) and portable document format (.pdf), which provides information concerning the GIS compilation, a geologic legend for the maps, as well as a “Getting Started” section. The data are useful for many purposes, including groundwater and surface water studies, other environmental studies, geotechnical investigations, land-use planning and mineral exploration. This data may be of interest to the land-use planning, consulting, aggregate/industrial mineral industry and development community as well as government geoscientists, resource scientists, conservation authorities, land-use planners and academic researchers. The files are on 1 CD. $20.00

Miscellaneous Release—Data 241
Post-Archean Mafic (Diabase) Dikes and Other Intrusions of Northwestern Ontario, North of Latitude 49°30′; by G.M. Stott and S.D. Josey. This digital data release comprises a GIS-compatible version of Preliminary Map P.3606, which shows Proterozoic mafic (diabase) dikes across northwestern Ontario, north of 49°30′. The map is based on a visual interpretation of diabase dikes using re-processed aeromagnetic data from regional and high-resolution surveys. The results provide an interpretation of the different dike swarms subdivided on the basis of dike orientation and some local dike age determinations. Digital files on this DVD include shapefiles; a GIS version of the map; seamless aeromagnetic map of the region showing the publicly available high-resolution aeromagnetic coverage across some greenstone belts, embedded in the regional aeromagnetic image; and a table of geochronology of selected diabase dikes. The data are on 1 dual-layer DVD. $25.00.

Enhancements to the Aggregate Resources Inventory Paper (ARIP) Series
The Aggregate Resources Inventory Program of the Ontario Geological Survey provides basic geological information on potential mineral aggregate resource areas, which can be used, for example, in land use planning strategies. Since its introduction in 1979, the program’s Aggregate Resources Inventory Paper (ARIP) series has identified the nature and extent of aggregate resources throughout the province. Maps accompanying the reports outline areas of potential for aggregate extraction. Initially published as hard-copy reports, the ARIP series has also been available digitally, over the past few years, in portable document format (PDF) from GeologyOntario.
We are now able to offer enhancements to the series. Tables in the report that provide details on aspects of the aggregate potential of an area (such as total sand and gravel resources, and total bedrock resources) are now available in spreadsheet format (e.g., Microsoft®Excel®). Similarly, ESRI® ArcGIS® files of the maps accompanying the reports are also available. These ArcGIS® files contain additional information on the aggregate resources of an area (such as deposit type and texture data for the sand and gravel resources map) that are not on the hard-copy maps.
The enhanced information and map files are available for download from GeologyOntario in a compressed (.zip) file, in the same location as the ARIP. The Aggregate Resources Inventory Map (ARIM) designation will not be continued for the digital map files. In future, these map files will be found only with the associated ARIP and will not be published as a separate series.
These enhancements to the ARIP series are effective June 2, 2009. Comments on these changes may be directed to the Senior Manager, Sedimentary Geoscience Section, Ontario Geological Survey.
Aggregate Resources Inventory Paper 183
Aggregate Resources Inventory of the United Counties of Leeds–Grenville, Southern Ontario; by Jagger Hims Limited, C. Gao and D.J. Rowell. 51p. $28.00.
Errata
In Open File Report 6226, Summary of Field Work and Other Activities 2008 (released December 8, 2008), the following errors were noted in Article 15, Characterization of Plutonic Suites in Cavendish Township, Grenville Province, by In-Situ Geophysical Measurements and Geochemistry in Table 15.1. Some of the values for 2 intrusive unit sampling sites—numbers 3 and 4, Galloway pluton and Junction pluton, respectively—were reversed. The values for the specific gravity; the magnetic susceptibility; and the average and median weight % K, ppm U and ppm Th were reversed. The sampling site number, unit name and UTM location, rock type and age for each of site 3 (Galloway pluton) and site 4 (Junction pluton) are correct and remain unchanged.
These errors have been corrected and a replacement page is available. If you would like a copy of this page, please contact Publication Sales and it will be sent to you free of charge. The corrected article is also available on the Mines and Minerals Division web site at http://www.MNDMF.gov.on.ca/mines/ogs/ims/pub/sfw/default_e.asp.
On Preliminary Map P.3607, Precambrian Geology of the Winisk Lake Area, Northwestern Ontario, released April 7, 2009, the geochronological age reported for sample site 4 in the northeast part of the map face should read “<2719 ± 2 Ma” not “2919 ± 2 Ma”. The age is correctly reported, however, in Table 2.
We regret any inconvenience these errors may have caused.

Discover Abitibi Initiative
The Discover Abitibi Initiative is a regional, cluster economic development project providing geoscientific investigations of the Western Abitibi Greenstone Belt in Ontario. The project has brought together funding partners FedNor, Northern Ontario Heritage Fund Corporation and the private sector to complete projects, which will further stimulate exploration activity and mining in this prolific belt. To support this successful endeavor, user stakeholders have provided the project ideas. The technical expertise to evaluate the projects has been provided by volunteers on the technical and management committees. Further information regarding this initiative can be found at www.discoverabitibi.com or by contacting the Timmins Economic Development Corporation by email at tedc@timmins.ca.
