The application of different analytical extractions and soil profile sampling in exploration geochemistry

Abstract:

This paper deals briefly with the principles of geochemical migration
in the secondary (soil, sediment) environment, a knowledge of which is
essential to a correct interpretation of exploration geochemical data.
Examples are given which illustrate that the principles which apply in
the more easily interpreted tropical areas, also apply in the more
complicated glaciated regions. Any person employing exploration
geochemistry in geomorphologically complicated areas, is well advised
to study data from strictly residual soil areas where the fundamentals
of geochemical migration are more easily observed. From this base it is
easier to understand the additional complications of geochemistry in
mountainous and glaciated terrain. Of the variety of exploration
geochemical techniques which can be used, this paper deals specifically
with two: soil profile sampling, and different strengths of acid
extraction of metal from samples. Examples from the different
environments are compared and contrasted.
