QUEST-South Project Sample Reanalysis

Report Components

Report Description
As part of Geoscience BC's 2009 QUEST-South Project, a selection of archived drainage sediment samples have been reanalyzed by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) by ALS Chemex (North Vancouver). These techniques provide a wide range of new analytical information at improved detection levels plus greater data compatibility with analytical methods currently being employed (Jackaman and Reichheld, 2009).

Geoscience BC Report 2010-4 includes new analytical results for a total of 8256 stream sediment samples that cover parts of NTS map sheets 082E, L, M and 092H, I, J, O, P. These government-funded surveys were originally conducted from 1976 to 1981 as part of the National Geochemical Reconnaissance (NGR) program (Lett, 2005). The new data has been carefully checked for analytical quality using blind duplicate samples and control reference material. When determined to be complete and accurate, the reanalysis data were merged with sample site location information acquired from the original survey published reports. It should be noted that although efforts have been made to include all samples from the target survey areas, there are gaps in the final data set due to missing archive material for a total of 280 samples.

The project was funded by Geoscience BC and managed by W. Jackaman (Noble Exploration Services Ltd.) in cooperation with M. McCurdy, J. Pinard and P. Friske of NRCan, and R. Lett and D. Lefebure of the BCGS.
