摘要
The near infrared spectrum has a characteristic sensitive to hydroxyl (OH-), etc., which can help us distinguish many kinds of altered minerals and their different crystallinity, such as hydroxyl-containing silicate minerals (epidote, amphibole, etc.), carbonate minerals (calcite, dolomite, etc.), individual minerals in phyllosilicates (clay mineral, chlorite, serpentine, etc.), sulphate minerals (alunite, jarosite, gypsum, etc.) and so on. Based on the knowledge of spatial distribution of altered mineral the models of altered mineral zonality can be built, offering the effective basis for the further work of this district and good results have been received by it.
