Basal till, humus and balsam fir twigs were collected in 1998 around known base metal skarn occurrences in the McKenzie Gulch area, northwestern New Brunswick. Samples of basal till and pebbles from till were collected at each of 117 sites. Balsam fir and humus were collected at 100 and 57 of these sites, respectively.
Basal till (~5 kg) and approximately 50 pebbles (>1 cm size fraction) from the till were sampled in hand-dug pits (0.5 – 1.0 m in depth), trenches or road cuts. Approximately 1 kg of humus was collected. Approximately 8-10 fresh balsam fir twigs with needles (200-250 g), each 35-40 cm long and comprising 5-7 years of growth were collected.
The data are published in New Brunswick Department of Natural Resources and Energy Mineral Resource Report 98-4.
Humus: <0.177 mm analyzed by INAA for 35 elements; by ICP-AES after HNO3-HCl digestion for Cu, Pb, Zn, Co, NI, Ag, Mn Fe, and Cd; by AAS afterHNO3-HCl digestion for Mo and V; for Sn by AAS after NH4I fusion and extraction into methyl isobutyl ketone containing trioctylphosphine oxide; Hg after HNO3-HCl digestion and later treatment with SnSO4-H2SO4; LOI and F after a sample sintered with sodium carbonate-potassium nitrate flux.Till: <0.063 mm (A. Pronk, pers. comm., 2005) by INAA; by ICP after HClO4-HNO3-HCl-Hf; by hydride ICP-ES for Bi, Se, Ge, and Te.
