Dossier Public 1289
Previous OF publication(s): 0563.2, 0563.1
Province / Territory: Yukon Territory
Funding Source: Federal (1978, 1979); Federal &Territorial (1985)
Year of Collection: 1978
# Lake sites: 0
# Stream sites: 959
Survey Area: 12247 km²
NTS Sheet(s): 105B
The regional stream survey for southern Yukon (NTS 105B) was conducted during the summer of 1978.
Open File 1289 presents analytical and statistical data for 8 elements plus loss-on-ignition obtained by re-analyzing stream sediments from 959 sites, collected at an average density of one sample per 12.8 km². Original analytical data selected from Open File 563.2 (published 1980) for 12 elements and uranium, fluoride, and pH values in concomitant waters are also included in this report.

Open File 563.2, released in 1980, included analytical values for uranium in stream waters not in the original release of 563.1 (1979).
Gold usually determined on 10-gram sample, allowing a detection limit of 1 ppb; sample weights less than 10 grams resulted in a detection limit of 2 ppb. Sample weights less that 5 grams not analyzed.
