[EN] Geochemical mapping represents an application of conventional geochemical methods to the knowledge of the natural environment. This is the most useful way to determine the current levels of geochemical amounts -geochemical baselines- to comprehend the spatial distribution and variability of the different elements, and to document variations in their levels in natural materials at the Earth surface. Those changes, usually are shown in geochemical distribution maps produced by geochemical mapping projects, can often indicate areas affected by possible anthropic pollution activities or even anomalies related to known or to unsuspected mineralizations. Nowadays, geochemical mapping is one of the main activities performed in the national geological surveys and organizations for several research fields. Following the recommendations included in the Final Report of the Project 259 for the International and National Geochemical Programs.
