This report presents a compilation of about 1,000 geochemical analyses of alluvial sediments, collected from stream- and river- beds, banks, and floodplains downstream from mines and mills of the Coeur d'Alene (CdA) silver-lead-zinc mining district in north Idaho. Methods of sample collection, preparation, and analysis are described. Locations of sample sites are shown on maps and listed in tables showing latitude and longitude (in degrees to four decimal places), sample-depth intervals (cm), sample descriptions, and chemical analytical results for as many as 40 chemical elements.
Results of these analyses are included in the report as appendices. They may be downloaded individually from the report, as .xls or .dbf files, from the table below.
