Bundle Description

Geochemical results of till samples collected in the Alma (NTS 21H/10), Hillsborough (21H/15), Waterford (21H/11) and Petitcodiac (21H/14) regions, New Brunswick.

The <63 micron fraction of till was analysed for Ag, 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 carried out by Chemex Labs Ltd. in Mississauga, Ontario.

The analytical data were obtained from Al Seaman in 2005 (in an MS Excel spreadsheet).
