Till New Brunswick 1985

Till sampling survey, northern Miramichi Zone, NTS 21O,P, New Brunswick, 1985.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till samples from 974 sites were collected over the northern Miramichi Zone in New Brunswick in 1985. The data are published in GSC Open File 2236. A final report on the Miramichi Zone, including stratigraphy and till geochemistry was published in GSC Bulletin 433. Some samples from 21O/15,16 were re-analysed and published in New Brunswick Department of Natural Resources and Energy Open File 2002-9.

Data Description: Paper report; digital data.

Quantities Analysed: <0.002 mm fraction analyzed by AAS after HCl:HNO3 (1:3) digestion for 10 elements; by colorimetric methods for As and W; by specific ion electrode for F; by CV-AAS and flameless-AAS for Hg; by XRF for Sn; by fluorometric method after HNO3 for U. <0.063 mm fraction by INAA for 11 elements; by CV-AAS for Hg; and by AAS after HCl:HNO3 (1:3) for As; by AAS after HCl-KClO3 for Sb; by fire assay-INAA for Au.

Project History

1985-1990 Northern and central New Brunswick regional till geochemical surveys 1985-1987.
  Regional till geochemical surveys were conducted in northern and central New Brunswick as part of a Quaternary geology and till geochemistry project. The main objective was to study the variability of the geochemistry of till overlying rocks over the Miramichi Zone and its vicinity. The Miramichi Zone was divided into 3 sub-zones (northern, central and southern) which appear to reflect specific geological and lithogeochemical contexts. The 3 sub-zones also make the readability of the geochemical data easier, as over 3500 samples were collected over the whole zone. The data are published in GSC Open Files 2236, 2237 and 2238.

1998-2002 North central New Brunswick till and soil sampling survey carried out in 1998-1999.
  Till and humus samples were collected in the Atholville-Charlo map area in north central New Brunswick in 1998-1999. One objective of the study was to determine the effectiveness of humus, relative to till, as a sampling medium for delineating geochemical dispersal patterns. The data are published in New Brunswick Department of Natural Resources and Energy Open File 2002-9. The dataset also includes reanalyses of till samples from previous surveys already published in N.B. Geological Notes Series P.M. 86-216 and 88-10 as well as GSC OF 2236).
