BC RGS stream sediment and water survey, NTS 104K, northwestern British Columbia, 1987.
(requires an Internet connection)
During the summer of 1987, helicopter (97%) and truck (3%) supported stream sediment and water collection was carried out in the Tulsequah area, northwestern British Columbia. Samples were collected from 847 sites at an average density of one site per 11.7 km2 throughout the 9,900 km2 survey area. Duplicate samples were routinely collected from a site once in each analytical block of twenty samples. The data are published in British Columbia Ministry of Energy and Petroleum Resources Regional Geochemical Survey RGS 20/Geological Survey of Canada Open File 1647.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Stream sediment samples ideally comprise 2 – 4 kg of sand size and finer inorganic material collected from low energy sites within the stream. Large Kraft paper sample bags were used to ensure sufficient fines were collected. Stream waters were taken using 250 mL Nalgene plastic bottles flushed out with water from the stream prior to collection of the sample.
