Bundle Description

Geochemical results of till samples surveyed in the Riley Brook region of New Brunswick are presented.  This area of New Brunswick corresponds to NTS map sheet 21 O/3.

The basal till fractions (< 63 micron) were analysed for As and Sb using atomic absorption spectrometry (AAS).  Hg was analysed using cold vapour atomic absorption spectrometry (Hg-CVAAS).  The samples were analysed for Au using fire assay neutron activation analysis (FA-NA).  The analyses were performed by Chemex Labs Ltd. in Mississauga, Ontario.

The analytical data were obtained from Mike Parkhill in 2005 (in an MS Excel spreadsheet).

The geochemical results of this survey were reported by A.G. Pronk and M. A. Parkhill, NBDNRE.

The data are published in New Brunswick Department of Forests, Mines and Energy Geological Notes Series P.M. 89-71.

Analytical Package Description

Laboratory: Chemex Labs Limited

Name: Chemex AAS (As, Sb) + Hg CV-AAS + FA-NA (Au) (more)

Till samples were dry sieved using an 8 inch sieve shaker.  The <63 µm fraction was analysed for As and Sb using atomic absorption spectroscopy (AAS).  Mercury analysis was performed by cold vapour atomic absorption spectrometry (Hg-CVAAS).  Au analysis was performed by Fire Assay-Neutron Activation Analysis (FA-NA).  The analyses were performed by Chemex Labs Ltd. in Mississauga, Ontario.
