Application of Airborne Hyperspectral Remote Sensing in Exploration for Sn ore in A-type Granite

As the second basin of China, Junggar, especially the east Junggar concentrates rich and wide varieties of polymetallic ore. In this paper, several Sn ores around Kamust are investigated and analysed to find atered minerals and their assemblage is related to Sn ore. SCASI-SASI-TASI data are used to extract those atered minerals information, and the thermal infrared data-TASI is used to distinguish the high SiO2 belts. The research result tells us that Sn ores close relate to fracture, hydromicazation and greisenization. Thus, high hydromicazation, muscovite and SiO2 associated to Sn ores. Base on this result, several Sn ore prognosis areas are delineated, and several of them develop Sn mineralization. In this paper, airborne hyperspectral data-CAS-SASI-TASI (parameters in Table 1) of east junggar region is used to analysis and forecasting favorable areas of Sn ore. The airborne remote sensing data not only has high spectral resolution, but also high spatial resolution (hereinafter referred to as the "high resolution"). [GRAPHICS] .
