Till sampling survey, central Miramichi Zone, NTS 21O,P,J, New Brunswick, 1985-1987.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Over 1700 till samples were collected in 1985-1987 in the central Miramichi Zone and vicinity in New Brunswick. The data are published in GSC Open File 2237. A final report on the Miramichi Zone, including stratigraphy and till geochemistry was published in GSC Bulletin 433. 89 samples from NTS 21O/2 were reanalyzed by XRF and published in GSC Open File 2246. 161 samples from NTS 21O/1 were reanalyzed by XRF and published in GSC Open File 2560.

Data Description: Paper report; digital data.

Quantities Analysed: <0.002 mm fraction 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. <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.

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.

1990-1993 North central New Brunswick till sampling survey carried out in 1990-1991.
  The project involved completing regional Quaternary geological studies, specifically mapping of Quaternary sediments and obtaining detailed information on till provenance and geochemistry. It was aimed at stimulating mineral exploration by providing new or updated geological information. In addition to new till data for the area, re-analyses of archived samples from M. Lamothe’s survey (Open File 2237) were carried out. The data are published in GSC Open Files 2246 and 2560.
