Survey Description


Approximately 450 humus, B-horizon soil and C-horizon till samples were collected in 1992 along the north and east ranges of the Sudbury basin in northern Ontario.  The data are published in Ontario Geological Survey Open File Report 6033.

Data Description:

Paper report; digital data released as MRD-61 (Miscellaneous Release-Data 61).

Quantities Analysed:

<0.177 mm fraction of humus, <0.063 mm fraction of B-horizon soil and C-horizon till by ICP-AES after aqua regia and also a phase selective leach for 30 elements, by hydride generation ICP-ES after aqua regia and co-precipitation with La(OH)3 for As, Sb, Bi, Se, T, and Ge, and by fire assay-ICP-MS for Au, Pt, and Pd.  Also selective extraction of "soluble organic" and amorphous Fe oxyhydroxide phases using various digestions and analytical techniques.  Birch twigs after ashing by INAA for 35 elements and by GF-AAS for Au, Pt, and Pd.

Geochem Maps Available:

Proportional symbol maps show regional and detailed dispersal of elements in humus, B-horizon and C-horizon till and the dispersal of pebble lithologies and selected heavy minerals in till.

Other Analyses:

Pebble lithologies; heavy mineral concentrate for gold grain counts and point counts.
