Survey Description


Centre lake bottom sediments were collected in the summer of 1977 from 3806 sites over an area of 17,400 km2 in the Meelpaeg Lake area, central Newfoundland.  The data are published in Newfoundland and Labrador Department of Mines and Energy Open Files NFLD/986 and NFLD/1222(an update OF that also contains F data).  Tungsten data were released in NFLD/1302.  Gold data for samples in NTS 12A/1, 2 were released along with other data from 12A in Open File NFLD/1801.

Data from parts of NTS 1M were released in Open File 1M/276 with data collected in other years from 1M and this Open File is superseded by Open File 1M/312 which contains reanalyses by INAA for all of NTS 1M.

Reanalysis by INAA of samples from NTS 2D, 11P and 12A were published with other samples from those areas in:

Sampling Procedure

Samples were collected from the central portions of lakes using a lead-weighted steel pipe-like sampler and winch mounted on a Bell 206A helicopter.
