Between 1996 and 1998, the BC Geological Survey carried out regional till geochemical surveys in the Adams Plateau area of central British Columbia. More than 1500 samples of glacial till were collected and analysed for trace elements and major oxides. The data results were released previously as BC Geological Survey Open Files.


Geofile 2005-18 is an overview of the techniques used to collect and analyse the samples, the regional ice-flow history and the distribution of iron (Fe2O3), calcium (CaO), titanium (TiO2), chromium (Cr2O3), arsenic (As), gold (Au), nickel (Ni) and copper (Cu) in the till samples. There is a close relationship of tillCr2O3 and TiO2 to the underlying geology demonstrating that till geochemistry can be used to identify host rocks favourable for mineralization in drift covered areas.  Numerous hill till Au, Cu and As values in the northwest part of the surveyed area may reflect concealed bedrock mineralization and potentially new exploration targets.  With the Geofile text are digital files in Excel format containing all of the element data.
