Element Dissolution Technique
Cu, Pb, Zn, Ni, Co, Mn, Ag


atomic absorption (AAS)


visual colorimetry
Mo HCl visual colorimetry


The data are published in geological report RG-163, Department of Natural Resources, 1975.  This report is the third of a series of 3 publications following a geological reconnaissance program in the Grenville Province, known as the "Grenville Project".
