Survey Description
In the summers of 2014, 2015 and 2016, a total of 260 till samples were collected during a study of the southern Core Zone area, Quebec and Labrador. In 2016, one sample was collected west of the main study area near the ice divide.
Where possible, samples were collected from hand-dug pits in active mud boils at a depth between 0.2 and 1.0 m. In areas south of the limit of discontinuous permafrost, till samples were collected by digging through the naturally developed soil profiles to sample unoxidized till (C horizon).
Two samples were collected at each site, a large till sample (7–13 kg) for recovery of indicator minerals and a ~3 kg sample for geochemical analysis, textural determinations, Munsell colour determination, and archiving.

The geographic extent of the survey is defined by the following polygons:
-
Covers NTS 23I (Woods Lake) and 23P (Lac Resolution) in Labrador and Quebec. The Quebec-Labrador border runs approximately east-west through the centre of the Core Zone study area. It is bounded to the east by 64°W longitude and to the west by 66°W longitude. Michikamau Lake is located in the southeast corner of the study area.
-
Covers a very small part of NTS 23O/8 (Lac Thompson; 1 sample) northern Quebec near the Quebec-Labrador border. It is located approximately 72 km northeast of the town of Schefferville. The sample was collected while investigating an ice divide in the area.
-
Covers a very small part of NTS 24A (Lac Brisson; 3 samples) in northern Quebec and a small part of 14D (Tasisuak Lake; 3 samples) in northern Labrador. The study area is located near Strange Lake, Labrador. The Quebec-Labrador border runs north-south through the western part of the study area.
