Prospecting for ore deposits by panning heavy minerals from river sands
Economic Geology and the Bulletin of the Society of Economic Geologists 56(7): 1250-1257
Notes that certain ore and indicator minerals such as scheelite (and wolframite), chromite, and hydrozincite may be transported by streams for surprisingly long distances. Panning and testing of heavy mineral concentrates can therefore be used for rapid reconnaissance of the mineral potential of relatively large areas, particularly in undeveloped regions. The application of the method in exploration for tungsten in north Pakistan is cited.
