Survey Description


176 till samples were collected in 1985 in the Letitia Lake area, central Labrador.  The data are published in Newfoundland Department of Mines and Energy Open File 13L/0069.

The samples were reanalyzed in ~2004 for a larger suite of elements and the data are published in Newfoundland and Labrador Department of Natural Resources Open File 13L/0121.

Data Description:

Paper report and maps.

Quantities Analysed:

<0.063 mm fraction by AAS after HNO 3 digestion and HCl leach for 11 elements; by X-ray fluorescence for 12 elements; by ion specific electrode for F; and by delayed neutron activation for U.

Geochem Maps Available:

Maps 89-to 89-124 show the dispersal of selected elements.

Samples from this survey were reanalyzed for fluoride and the data are published in a compilation (Open File LAB/1778) with samples collected from across Labrador between 1983 and 2004.
