Survey Description


During the winter of 1983-1984, a helicopter supported lake sediment sampling survey was conducted by the SIAL company in the Schefferville area, Quebec.  The area covers 9200 km2.  A total of 3555 samples were collected at an average density of 1 sample per 2.6 km2. In most cases, sampling was conducted on lakes larger than 1 km.  Samples were analyzed for:

 

Element Dissolution Technique
Ag, Al, B, Ba, Be, Ca, Cd, Ce, Co, Cr, Cu, Eu, Fe, Hg, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sc, Sm, Sn, Sr, Th, Ti, V, Y, Zn, Hg   atomic absorption (AAS)
Loss on ignition (LOI)    
U   paper chromatography
pH   ion selective electrode (ISE)

 

The data are published in Open File MB 86-50, Department of Energy and Resources, 1986.  From the same author, data for gold and arsenic were also published in MB 84-07 et MB 85-22A et B.  Additional data are published in MB 87-32.
