Uses of WorldView-2 Multispectral Data in Extracting Potential Iron Mineralization Zones

A test site in West Kunlun area, China has been established to study the applications of WorldView-2 multispectral data to iron oxide minerals mapping. An iron oxide minerals distribution map was mapped by Spectral Matched Filtering (SMF) technique after the image data had been processed by atmospheric correction. The Gothite spectrum from USGS spectral library was chosen as the iron oxide mineral end member. And acoording to the result of SMF, field work was carried out and two potential iron minerlization zones were found in the study area. The study indicate that SMF method for WorldView-2 multispectral data holds promise for iron oxide minerals mapping in some iron ore deposits. And further analysis is required in different geologic environments in West Kunlun area to validate WorldView-2 multispectral data as a useful aid to land surface mapping.
