Survey Description

Helicopter-supported sample collection was carried out during the summer of 1996 in the McConnell Creek map area, British Columbia.  A total of 1034 stream sediment and 1034 stream water samples were collected from 976 sites.  The average sample site density was 1 site per 13 km2 over the 13,000 square kilometre survey area.  Field duplicate samples were collected in each analytical block of twenty samples.  Samples were not collected in Tatlatui Provincial Park.  The data are published in British Columbia Regional Geochemical Survey RGS 45.

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

Sampling Procedure

Primary and secondary drainage basins with catchment areas of less than 10 km2 were sampled.  Sediment samples weighing 1 to 2 kg were obtained from the active stream channel.  Samples were primarily fine-grained material mixed with varying amounts of coarse sand, gravel and organic material.  Surface water samples were collected in 250 mL bottles and suspended solids were excluded where possible.
