Abstract The application of the aerosol theory and technology to deep prospecting is the basic problem discussed in this paper. Minerals from the depth can pass through the overburden of the ore deposit and reach the earth's surface. This process is mainly implemented by the transfer of the gas which carries plasmid upward from the depth. The basic condition of this transfer is that plasmid could be stably suspended in the gas and then flow. The aerosol theory suggests that plasmids in the range of 0.1～2.5 μm in diameter are the most stable ones in gas. Plasmids in the smaller or coarser sizes cannot be suspended in the gas for a long time; another point of the aerosol theory is that the solid plasmid which is less than 2.5 μm in diameter cannot be produced by mechanical milling. These two points of aerosol theory constitute the foundation of the view that the deep metal mine could generate aerosol levels plasmid,then the plasmid enters gas to transfer upwards. The aerosol theory and technology were applied in the prospecting test of the Jinwozi concealed gold deposit in Xinjiang. The results showed that,at the top of the No. 210 concealed deposit and above the inclined plane of the deposit,there is an obvious Au anomaly and a satellite elements anomaly,characterized by high anomaly contrast value and large exposed area. This experiment proved that the method of extracting the aerosol plasmid absorbed on the surface soil and then making element analysis has a good ore prospecting effect.
