Mineral resources are important material basis for the survival and development of human society. The development of
hyperspectral remote sensing technology, which has made direct identification of minerals or mineral aggregates become
possible, paves a new way for the application of remote sensing geology. The West Junggar region is located Xinjiang
west verge of Junggar, with ore-forming geological conditions be richly endowed by nature and huge prospecting
potentiality. The area has very good outcrop exposure with almost no vegetation cover, which is a natural test new
method of remote sensing geological exploration. The characteristic of rock and mineral spectrum is not only the
physical base of geological remote sensing technical application but also the base of the quantificational analysis of
geological remote sensing, and the study of reflectance spectrum is the main content in the basic research of remote
sensing. In this study, we collected the outdoor and indoor reflectance spectrum of rocks and minerals by using a
spectroradiometer (ASD FieldSpec FR, ASD, USA), which band extent varied from 350 to 2,500 nm. Basin on a great
deal of spectral data for different kinds of rocks and minerals, we have analyzed the spectrum characteristics and change
of seven typical mineral rocks. According to the actual conditions, we analyzed the data noise characteristic of the
spectrum and got rid of the noise. Meanwhile, continuum removed technology was used to remove the environmental
background influence. Finally, in order to take full advantage of multi-spectrum data, ground information is absolutely
necessary, and it is important to build a representative spectral library. We build the spectral library of rocks and
minerals in Hatu, which can be used for features investigation, mineral classification, mineral mapping and geological
prospecting in Hatu Western Junggar region by remote sensing. The result of this research will be significant to the
research of accelerating Western Junggar mineral exploration.
