Survey Description
During the 1999 field season, approximately 1100 till samples were collected in the Hodges Hill area between Grand Falls in the south and Fortune Harbour to the north, central Newfoundland. Samples were collected mostly from hand dug pits 0.3 -1.3 m deep, from the C-horizon where possible. Where this was not obtainable, BC or B horizons were sampled. There was a 2-4 km spacing between sites. Duplicate samples were taken at 51 sites. The data are published in Newfoundland and Labrador Department of Mines and Energy Open File NFLD/2704.
Data Description:
Paper report with data diskette.
Quantities Analysed:
<0.063 mm fraction of till by ICP-ES for 29 elements (after digestion in a mixture of HF-HCl-HClO4); by AAS (after digestion in nitric acid) for Ag; by INAA for 28 elements.
Geochem Maps Available:
Proportional dot maps showing distribution of elements in till.
Samples from this survey were reanalyzed for fluoride and the data are published in a compilation (Open File NFLD/3344) with samples collected from across the province between 1985 and 2017.
