Survey Description


Till sampling was carried out in 1986 on the central portion of the South Mountain Batholith (SMB), central Nova Scotia.  Samples were collected on a 2 km 2 grid from beneath the placon and/or B-horizon zone at an average depth of 1 m.  In most cases till was sampled although ice contact deposits or residuum were locally collected.  Glacial deposits were sampled primarily in road cuts and hand-dug pits.  The data are published in Nova Scotia Department of Mines and Energy Preliminary Maps 87-013, 88-052.  A compilation of the geochemistry from the entire SMB area can be found in Nova Scotia Department of Mines Open File Report 90-006.
