Open File 1290



Open File:  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

Survey Type:  Regional Stream Survey
# 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.

Other information:

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.
