Dossier Public 1290
Previous OF publication(s): 0564.2, 0564.1
Province / Territory: Yukon Territory
Funding Source: Federal (1978, 1979); Federal &Territorial (1985)
Year of Collection: 1978
# Lake sites: 0
# Stream sites: 876
Survey Area: 11870 km²
NTS Sheet(s): 105F
The regional stream survey for southern Yukon (NTS 105F) was conducted during the summer of 1978.
Open File 1290 presents analytical and statistical data for 8 elements plus loss-on-ignition obtained by re-analyzing stream sediments from 876 sites, collected at an average density of one sample per 13.6 km². Original analytical data selected from Open File 564.2 (published 1980) for 12 elements and uranium, fluoride, and pH values in concomitant waters are also included in this report.

Open File 564.2, released in 1980, included analytical values for uranium in stream waters not in the original release of 564.1 (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.
