NTS 103 I/J - Terrace/Prince Rupert


BC RGS 1/42 /  GSC OF 772/734  /  GBC R2008-11

The Terrace/Prince Rupert (NTS 103I/J) reconnaissance-scale stream sediment and water survey was completed in 1978 and the resulting field and analytical data were released in 1979. A total of 2253 sediment and 2237 water samples were collected from 2128 sample sites.

 

As part of the RGS Archive Program, 2245 archived sediment pulps were re-analyzed by epithermal INAA and this new data along with original survey results were re-published in 1995.

 

In December 2008, Geoscience BC released the reanalysis of archived stream sediment samples by inductively coupled plasma mass spectrometry (ICP-MS). Geoscience BC Report 2008-11 includes results from the original 1978 survey, instrumental neutron activation analysis (INAA) data released in 1995, and the new ICP-MS data.
