Contents

New analytical data (aqua-regia and 4-acid digestions followed by ICP-MS) from the re-analysis of lake sediment samples, collected from 362 sites in the Bancroft Ontario area (NTS 31-C13, 031-D09 & 16, 031-E01 and 031-F04) in 1976 and 1982, are presented in this Geological Survey of Canada Open File. Field observations with accompanying sediment and water analytical data originally reported in GSC Open Files 899 and 900 are included in this report.

This work was undertaken under the auspices of the Bancroft geo-environmental U-REE model activity within the Environment Geoscience Program.  The objective of this activity is to develop a geo-environmental model for U-REE deposits in the Grenville Geological Province to support sustainable development of new mineral resources and to predict the sources, transport and fate of contaminants, as well as develop protocols to assess background conditions in regions subject to mineral development.
