Title: Critical Survey of Recent Developments in Geochemical Prospecting

Author(s): Sylvain J. Pirson (2)


A critical study of the respective advantages and disadvantages of the two current geochemical prospecting procedures is presented. It is particularly pointed out that soil analysis has only as advantage a relatively simple field procedure but in view of the complexity of the material analyzed, it is difficult, if not impossible, to reduce results to a common basis of comparison. Further limitations placed on soil-analysis prospecting are the persistence of the halo patterns and the shielding effect of shallow beds bearing oil and/or gas. Soil-air sampling is not affected by these limitations to as high a degree as soil sampling and it is therefore recommended that it should be given further serious trials regardless of the fact that it requires a more complex field proce ure.
