Surficial Geochemistry

Open File Report 6320
Results of Regional Till Sampling in the Chapleau Area, Northern Ontario; by C. Gao, 148p. Indicator mineral grain counts and geochemical and compositional data are available as Miscellaneous Release—Data 331 (see below). $40.00.

Miscellaneous Release—Data 331
Indicator Mineral and Till Bulk Sample Geochemistry Data, Chapleau Area, Northern Ontario; by C. Gao. This digital data release presents the results of a regional till sampling survey undertaken in the Chapleau area, northern Ontario. The data include heavy mineral grain counts for kimberlite indicator minerals (KIMs), metamorphic/magmatic massive sulphide indicator minerals (MMSIM®*) and gold, as well as geochemistry of the <0.063 mm fraction of the bulk sample. The data are being released in conjunction with Open File Report 6320, available separately. The files are provided in 20 Microsoft® Excel® 2010 (.xlsx) spreadsheets that contain information on sample site locations, sample processing data, gold grain counts, KIM and MMSIM®* grain data, electron probe microanalyzer results for KIM and MMSIM®* grains, clastic lithology data, and geochemical data for the <0.063 mm fraction of the bulk sample; and as well, 1 file in portable document format (.pdf), containing binocular microscope descriptions of nonkimberlitic boulders of mantle origin. The data are available on 1 CD. $20.00.

Miscellaneous Release—Data 340
Stream Sediment and Water Geochemical Data, Lake Erie Tributaries, Ontario; by H.E. Burke. This digital data release provides stream sediment and water geochemical data, limnological data and quality-control data, collected from a total of 208 sample sets from 102 sites during 4 different seasons along Lake Erie’s north shore and Lake St. Clair’s eastern shore by the Ontario Geological Survey in collaboration with the Ontario Ministry of Agriculture, Food and Rural Affairs. Seasonal data are provided for 52 sites from 11 quaternary watersheds. This release includes a background document describing the sampling methodology, sample preparation protocols, geochemical analytical methods and quality-control regimes. Stream sediment and water samples were analyzed by inductively coupled plasma atomic emission spectroscopy and inductively coupled plasma mass spectrometry for more than 60 elements. Stream sediment samples were also analyzed for phosphorus fractions and stream waters for inorganic anions and nitrogen by ion chromatography. Colorimetric methods were used to determine phosphorus and nitrogen fractions. All location information is presented as geographic co-ordinates (latitude and longitude) in the World Geodetic System 1984 (WGS84) and Universal Transverse Mercator (UTM) co-ordinates using North American Datum 1983 (NAD83) in Zone 17. Data are available as 6 Microsoft® Excel® 2010 (.xlsx) workbook files, one Microsoft® Access® 2010 (.accdb) database file containing sample data and preformatted queries to facilitate data extraction and 1 background document in portable document format (.pdf). The data are available on 1 CD. $20.00.
