Till British Columbia 1997

Till sampling survey, NTS 93F/5,12, central British Columbia, 1997-1998.  


British Columbia Ministry of Energy and Mines, Energy and Minerals Division, Geological Survey Branch

Survey Description

273 till samples were collected in 1997-1998 in the Marilla-Tetachuck Lake area of the Nechako Plateau in central British Columbia. The samples were collected at an average density of 1 sample per 3.5 km2. The data are published in British Columbia Geological Survey Open File 2002-11. Higher density sampling was conducted in areas of perceived higher mineral potential and around known mineral prospects. These data were not included in the regional data set.

Data Description: Paper report with data lists and data on diskette. Report can be downloaded.

Quantities Analysed: <0.063 mm fraction by INAA for 35 elements; by ICP-ES after aqua regia digestion for 30 elements; by flameless AAS for Hg.

Geochem Plots Available: Proportional dot maps showing dispersal for most elements.

Project History

1996-2002 Nechako NATMAP, central British Columbia, 1996-2000.
  Till geochemical sampling was carried out in 1996-1998 in the Nechako Plateau area of central British Columbia. It was part of a multidisciplinary study including Quaternary and bedrock geology mapping and stratigraphy and was a joint collaboration between the Geological Survey of Canada, the British Columbia Geological Survey and universities. The till geochemistry component of this project will provide baseline information on the mineral potential of the region and on the natural variability of metal concentrations in the surficial environment. The data are published in British Columbia Open File 2002-11 and Geological Survey of Canada Open File 3687. This project also includes a compilation of all published and unpublished data from the Nechako River map area which can be found in Geological Survey of Canada Open File 4166.
