Abstract

Abstract The objective of geochemical exploration is to detect anomalous concentrations of ore elements and evaluate their ore potential. Methods for the detection and evaluation of geochemical anomalies related to exposed deposits are now rather well developed. Recent successes in the development of geochemical exploration methods for blind and shallowly covered hydrothermal mineralization deserve special consideration. They are based on the characteristic features of composition and on the arrangement of primary geochemical haloes. Primary haloes are normally much larger than orebodies proper and thus extend the effective area for anomaly evaluation several fold as compared with ore occurrences themselves.
