Till New Brunswick 1985

Till sampling survey, southern Miramichi Zone, NTS 21J,G, New Brunswick, 1985.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

873 samples were collected in 1985 from 704 sites in the southern Miramichi Zone and vicinity, New Brunswick. The data are published in GSC Open File 2238. A final report on the Miramichi Zone, including stratigraphy and till geochemistry was published in GSC Bulletin 433.

Data Description: Paper report; data files on diskette.

Quantities Analysed: <0.002 mm fraction analyzed by different laboratories different years: (1) by AAS after HCl:HNO3 (1:3) for 10 elements; by colorimetric method for As; by specific ion electrode for F; by colorimetric methods for As and W; by fluorometric method for U; and by XRF for Sn. and (2) ICP-AFS after HCl:HNO3 (1:3) for 11 elements; by specific ion electrode for F; by flameless-AAS for Hg; by fluorometric method for U; by colorimetric method for W. <0.063 mm fraction by INAA for 11 elements; by CV-AAS for Hg; by AAS for As and Sb; and by fire assay-INAA for Au.

Geochem Plots Available: Proportional symbol maps showing dispersal of Cu, Pb, Zn, Sn, W, As, U, Hg in the <0.002 mm fraction and As, Sb, and Au in the <0.063 mm fraction.

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.
