Survey Description


During the summer of 1988, a helicopter supported lake sediment sampling survey was conducted by Sial Compagnie internationale de géophysiques inc., in the Havre-St-Pierre area, Quebec.  The area covers 50,500 km2.  The sampling was done using a probe.  A total of 5490 samples were collected and two grids were used: one sample per 2.5 km2and one per 13 km2.  Generally, sampling was done on lakes wider than 1 km.

The <177 micron fraction was analyzed for:

 

Element Dissolution Technique
Ag, Al, As, Au, B, Ba, Be, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Eu, Fe, Hg, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Sc, Se, Sm, Sr, Th, Ti, Tm, U, V, W, Y, Zn   inductively coupled plasma emission (ICP-ES) or flameless atomic absorption (F-AAS)
Loss on ignition (LOI)    
pH   selective electrode

 

The data are published in Open File MB 89-19, Department of Energy and Resources, 1989.  Geochemical maps are published in Open File MB 89-46.
