Survey Description


In 2012 and 2013, till samples were collected at 1028 sites in north central Newfoundland:

 

NTS Map Sheet Name Number of Till Samples
12H/01 Dawes Pond 189
12H/02 The Topsails 40
12H/07 Sheffield Lake 448
12H/08 Springfield 350
12H/10 Hampden 1

 

Samples were collected from the C-, BC- or B- soil horizon from pits, ditches, roadcuts, mudboils and quarries.  Sample spacing was controlled by access and presence of till, but was generally one sample every 1 km along all primary and secondary roads, and one sample every 4 km2 for helicopter-supported sampling.

The data are published in Newfoundland and Labrador Department of Natural Resources Open File 12H/2212.

This report also includes data for 276 samples from earlier surveys to provide complete sampling coverage for the area.

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.
