The present paper deals with the techniques and effects of applying the high-precision aerogeophysical integrated survey to searching for gold,potash salt and groundwater and conducting lithostructural mapping,with the emphasis placed on the following aspects:the application of Fparameter and gray systematic theory to the prognosis of gold deposits;the utilization of linear regression combined with principal component analysis to eliminating K₂O interference and delineating potash prospecting targets, the use of airborne electromagnetic -45° phase method to dividing water qualities,estimating water quantity and prospecting for groundwater;the employment of aeromagnetic,gravity and gamma spectral integrated information to conducting lithostructual mapping.
