Survey Description


Till sampling was carried out in 1985 in the Sambro, Halifax, Mt. Uniacke and Chester map areas, on the eastern portion of the South Mountain Batholith (SMB), central Nova Scotia.  Samples were collected on a 2 km2 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 87-011, 87-012 and 87-013.  A compilation of the geochemistry from the entire SMB area can be found in Nova Scotia Department of Mines Open File Report 90-006.
