The remote sensing measurement of the surface SiO2content has important geological significance .An empirical formula for estimate SiO2content was established based on the correlation between ASTER thermal infrared data and tested Si element from NITON sites in Abra, Australia. The average error of estimated SiO2content is about 15%. ASTER silica alteration derived from SiO2content has good indicative function to find galena. Combined with other prospecting factors as bouger gravity, transient electromagnetic and so on, three vision prospecting targets were optimized, which need more exploration works.
