Resumen
The nature of geochemical anomalies is discussed on a speculative basis. Anomalies
are classified as independent or as additive, depending on their spatial relation to the
background population. The additive anomalies, which are more commonly encountered
in geochemical exploration, cannot be separated from the background, in a composite
population, by extracting straight lines from curved cumulative frequency graphs, because
the cumulative frequency of the distribution of the additive component of an anomaly
plots as a curved line on normal and lognormal probability paper.
