Alteration minerals and silicification are typically associated with a variety of ore mineralizations and could be detected using multispectral remote sensing sensors as indicators for mineral exploration. In this investigation, the Visible Near-Infra-Red (VNIR), Short-Wave Infra-Red (SWIR), and Thermal Infra-Red (TIR) bands of the ASTER satellite sensor derived layers were fused to detect alte…
Identification and delineation of alteration minerals and regolith play an important role in the discrimination of metallic and non-metallic minerals and are also significant for metallic and non-metallic mineralization zone identification. In this work, altered minerals and gossans have been identified in and around the Askot area in eastern Kumaon Himalaya using hyperspectral data. Analysis o…
