The past few years have seen an increasing application of computer-based procedures in the processing and interpretation of geochemical data. In many cases this has been carried out by non-geologists using large, general purpose computers remote from

In areas of exotic overburden there is frequently no geochemical relationship between mineralized bedrock and the overlying material. Some species of vegetation have the capacity to absorb metals from groundwater via their extensive root systems and

The applicability of geochemical exploration procedures in previously glaciated areas is largely a function of the nature of the glacial sediments. A considerable diversity of glacial sediments and landforms results from a phase of glaciation, these
