Abstract: The air particles of Fankou lead-zinc deposit were collected with transmission electron microscopy grids. Through the transmission electron microscopy,it is discovered that there are a large number of air particles with size of less than 200 nm in the air of Fankou lead-zinc deposit. These particles are quite different from industrial emissions,vehicle exhausting,construction dust particles in morphology and elemental composition. So these particles may be inextricably related with the deposits and its exploration. It is primarily considered that the existence of underground ore body will have an impact on the air particles. The discovery means that an effective discriminating analysis can be made to discover the underground ore-bodies in new space from judging the special matters,air particles.
