Open File 2037

Open File:  2037
Previous OF publication(s):  0904, 0560
Province / Territory:  Newfoundland & Labrador
Funding Source:  Federal and Provincial (1979 and 1989); Federal (1983)
Year of Collection:  1978

Survey Type:  Regional Lake Survey
# Lake sites:  1553
# Stream sites:  0
Survey Area:  14400 km²
NTS Sheet(s):  023I, 023J, 023O

The regional lake survey for west central Labrador (parts of NTS 23I, 23J, 23O) was conducted during the summers of 1978 and 1982.

This report presents new data for gold and 25 other elements obtained by re-analyzing lake sediments from 1 553 sites, collected at an average density of one sample per 13 km². Original analytical data selected from Open Files 560 and 904 (published 1979 and 1983 respectively) for 16 elements in sediments, and uranium, fluoride, and pH values in concomitant waters are also included in this report.

The original reconnaissance surveys were managed by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy under the Canada - Newfoundland Agreement on a Uranium Reconnaissance Program (1976-1982) and the Canada - Newfoundland Cooperative Mineral Program (1982-1984).

The reanalysis program was undertaken under theCanada-Newfoundland Mineral Development Agreement (1984-1989).

E.H.W. Hornbrook directed the survey.

P.W.B. Friske coordinated the operational activities of contract and Geological Survey of Canada staff.

M. McCurdy edited open files and coordinated production.

A.C. Galletta managed the digital geochemical data and provided computer processing support.

H. Gross developed microcomputer software to produce data listings and summary statistics.

C.C. Durham and P. Doyle provided technical assistance.

Computing services provided by the Computer Science Centre, EMR.

Plotting was done by Canada Lands Data Systems staff at Environment Canada, Hull, Quebec.
