A main limitation of geochemistry is that we never know weather a low value of gold in sample X is there because there is no gold or because the source of mineralization is too far away or too deep for the technique used. In geochemical surveys the actual value of a sample is not as important as its difference with other surrounding samples. This difference is known as gradient, a term more frequently used by geophysicists. I present here a simple method to quickly identify gradient areas that may be due to the presence of a true geochemical anomaly using Excel. P. Geo. Ricardo A Valls, M.
