Abstract
In recent decades, multispectral and hyperspectral remote sensing data provide unprecedented opportunities for the initial stages of mineral exploration and environmental hazard monitoring [...]
Highlights
The principal component analysis (PCA) and band ratioing techniques are applied to ASTER and Sentinel-2 datasets for lithological and hydrothermal alteration mapping
Landsat Enhanced Thematic Mapper+ (Landsat-7 ETM+), Landsat-8, and ASTER datasets were used to detect hydrothermal alteration zones associated with epithermal gold mineralization using band ratio, relative absorption band depth (RBD) and PCA techniques
The sympathetic and judicious comments delivered by the reviewers enhanced each of the papers published in this special issue, which came to fruition only because they were willing to volunteer their time and attention
Summary
Multispectral and hyperspectral remote sensing data provide unprecedented opportunities for the initial stages of mineral exploration and environmental hazard monitoring. Identification of host-rock lithologies, geologic structural features, and hydrothermal alteration mineral zones are the most conspicuous applications of multispectral and hyperspectral remote sensing satellite data for mineral exploration in the metallogenic provinces and frontier areas around the world [1,2,3,4,5,6,7,8,9,10,11]. The achievements of articles presented in this special issue are summarized
