Geochemical exploration has become increasingly attractive as a new technique of detecting ore concealed beneath a mantle of organic debris, soils, or barren rock, and of mapping geological structures. Geochemical prospecting for minerals is based on systematic measurements of chemical properties of naturally occurring materials such as water, stream or lake sediment, soil, vegetation, rock, and soil-gas. This technique is available for use in both reconnaissance surveys and detailed ones. Some element or a group of elememts in a low concentration is commonly involved in the technique, and sometimes stable isotopes or fluid inclusions are done. Some basic principles and concepts useful for the discovery of abnormal chemical patterns related with mineralization are discussed in this paper. In addition, new techniques using sulfide minerals and a soil-gas called "Fingerprint" are described.
