Precambrian Geoscience

Miscellaneous Release—Data 298
Ontario Rhyolite Database—Northwestern Ontario and the Grenville Province; by B.R. Berger and J.E. Chartrand. This digital release is a compilation and interpretation of rhyolite occurrences in northwestern Ontario and the Grenville Province. This digital data set provides information on areas where rhyolite is identified by geology or geochemistry in northwestern Ontario and the Grenville Province. This publication complements the data set on the compilation and interpretation of rhyolite occurrences in northeastern Ontario, Miscellaneous Release—Data 281, Northeastern Ontario Rhyolite Database. The data are presented in geodatabase (.mdb) and shapefile (.shp) formats (created using ESRI® ArcGIS® 9.3) on a colour geology base derived from Miscellaneous Release—Data 126–Revised, 1:250 000 Scale Bedrock Geology of Ontario. The data comprise a polygon layer containing outlines of rhyolite and “felsic metavolcanic rocks”; geochemistry, geochronology and mineral occurrence layers; and Microsoft® Excel® 2003 (.xls) files containing geochronological data and geochemical analyses. Locations of point source rhyolite occurrences are inferred from the locations of the geochemical samples. Location data are provided in the latitude and longitude as well as Universal Transverse Mercator (UTM) projection and grid system, zones 15, 16, 17 and 18, North American Datum 1983 (NAD83). Data are available on 1 CD. $20.00.

Sedimentary Geoscience

Open File Report 6278
Shale Resources of Southern Ontario: An Update; by D.J. Rowell. Geochemical, mineralogical and brick testing results are available as Miscellaneous Release—Data 301 (see below). 46p. $12.00.

Open File Report 6281
Mine Centre Area Lake Sediment and Water Geochemical Survey, Northwestern Ontario; by R.D. Dyer and H.E. Burke. Geochemical data are available as Miscellaneous Release—Data 296 (see below). 179p. $24.00.

Miscellaneous Release—Data 296
Lake Sediment and Water Geochemical Data from the Mine Centre Area, Northwestern Ontario; by R.D. Dyer and H.E. Burke. Deep and shallow lake sediment geochemical data, and lake water geochemical and quality data, including quality-control data, collected from a survey of 1726 sites from the Mine Centre area, are being released in conjunction with Open File Report 6281. Data are available as Microsoft® Excel® 2003 (.xls) format files on 1 CD. $20.00.

Miscellaneous Release—Data 301
Geochemical, Mineralogical and Brick Testing Results for Shale Resources of Southern Ontario; by D.J. Rowell. This data release, released in conjunction with Open File Report (OFR) 6278, Shale Resources of Southern Ontario: An Update, contains brick testing results for the historical brick and tile manufacturing shale formations, collected and collated by the Ontario Geological Survey (OGS) over many years and at various locations throughout southern Ontario. Also presented in this release are the results of geochemical and mineralogical testing on these same shale formations. The test results are provided in tables in Microsoft® Excel® 2003 (.xls) format. The release also includes an ESRI® ArcGIS® map that displays the geographic distribution and location of these samples. The map is also provided in portable document (.pdf) format. Many of these test results have been published in a variety of OGS reports; however, with the release of OFR 6278, it is important to provide this information digitally and in a single, summarized release. Available on 1 CD. $20.00.

Miscellaneous Release—Data 302
Preliminary Data Release, Southern Ontario Stream Sediment Geochemistry Survey; by R.D. Dyer and H.E. Burke. Stream sediment data, including results from particle size analysis and aqua regia digestion/inductively coupled plasma (ICP) spectrometric analysis for inorganic (metals) chemistry, including quality control data, collected from a survey of 2133 sites in southern Ontario are being released. Data are available as Microsoft® Excel® 2003 (.xls) files on 1 CD. $20.00.
