Soil and till sampling, NTS 21J/14, 21J/15, 21O/2, 21O/3, northwest New Brunswick, 1983.
(requires an Internet connection)
During the summer of 1983, B-horizon and till samples were collected at 174 sites in the Trousers Lake area, northwest New Brunswick. At each site, a hole was dug with a spade into parent material. B-horizon samples weighing between 1.5 and 2.5 kg were collected. C-horizon samples were collected in 12 L buckets and sieved and panned in the nearest brook or lake. If digging the hole was impossible due to large boulders or there was a lack of parent or B-horizon material, the sample location was moved up to 200 m in any direction. The data are published in New Brunswick Department of Natural Resources Report of Investigation No. 20.
<0.180 mm fraction of B-horizon digested with nitric acid (HNO3) analyzed for Cu, Pb, Zn, Ag, Mn, Co, Ni, Fe by AAS and for Mo by colourimetry. <0.180 mm fraction of C-horizon samples were fused with potassium bisulphate and leached with concentrated HCl. Samples analyzed for U by neutron activation- delayed neutron counting and Au by neutron activation-gamma spectroscopy. W also analysed, but no method given.

The geographic extent of the survey is defined by the following polygons:
Covers parts of NTS 21J/14 (Plaster Rock), 21J/15 (Tuadook Lake), 21O/2 (Serpentine Lake) and 21O/3 (Riley Brook), the Trousers Lake area, northwest New Brunswick. Highway 108 runs east-west through the southern part of the study area.
