Geological Characteristics and Industrial Significance of Mapo Quartzite Deposit, Shaanxi

In this paper, the regional geological characteristics, ore shape and type, mineral characteristics, ore chemical composition, quality of Mapo quartzite deposit were introduced. The deposit genesis was analyzed and the deposit was believed to be the sedimentary-metamorphic quartzite mine. The ore has complied with the quality of first-second degree of flat glass silicon material and can be used as the solar energy polycrystalline silicon material after purification.
