Abstract: The nanoscale minerals extensively existing around orebody can be transported from depth of hundreds to thousands meters to the surface by the geogas,and it can seized near the earth's surface.Therefore nanoscale minerals are closed related to direct information from orebogy.By analyzing constitution and aggregation situation et al of nanoscale minerals,the results can be used to prospect hidden minerals.The research progress and some applied examples in prospecting minerals are introduced,and the existing problems are discussed,and the further studies are predicted in this paper.
