Gold Prospecting Methods

Geochemical ProspectingWet Chemical MethodsGeophysical ProspectingClaim to Mineral Discovery and ExplorationGeochemical prospecting is based on systematic measurement of chemical properties of rock, soil, glacial debris, stream sediment, water, or plants. The chemical property most commonly measured is the content of a key trace element. Zones in the soils or rocks of comparatively high, or anomalous, concentrations of particular elements may guide the prospector to the elements in rocks or soils that constitute a geochemical anomaly (different from normal). The actual amount of the key element in...
