Survey Description

During the summer of 2005, stream sediments and water samples were collected from 174 sites in the Yukon portion of the Flat River map sheet.

The data are published in Geological Survey of Canada Open File 5329/Yukon Geological Survey Open File 2006-18.

This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.

Sampling Procedure

NGR stream sediment and water

At each site a pre-labelled Kraft paper bag was two-thirds filled with silt or fine sand collected from the active stream channel.  In practice, the silt sample was collected after water samples were collected but before a bulk sediment sample.  Handfuls of silt from various points in the active stream channel were collected while gradually moving upstream.  A moss mat sample was sometimes collected when a suitable sample was scarce or absent.

At every site, waters were sampled mid-channel, from flowing water where possible.  At sites where sediments were taken for heavy mineral concentration (approximately every second site) two water samples were generally collected.  Samples were collected in 125 mL Nalgene bottles.  The bottles were rinsed two or three times before collecting the sample.
