摘要

Ore prediction based on the Operational Land Imager (ETM+) image within the heavily vegetated and sediments-covered areas is always a difficulty for geological remote sensing. Here, we report a new scheme for extraction of near-ore alteration information in such localities: Terrain Analysisprincipal component analysisFractalSpatial Overlay and the Fe3+-OH- integrated anomalies that are punctate and probably ore-caused were reasonably exposed. Findings showed a satisfactory result that the spatial, if not genetic, dependency relationship between the remotely sensed anomalies and geochemical anomalies, as well as the ore-controlling geological bodies, is significant. However, no substantial spectral anomalies of vegetation immediately responsible for local mineralization and alteration were detected. This study may have contributed a useful case study for in-depth remote sensing exploration.
