Processed visible near-infrared and short wave infrared reflectance data of ASTER bands are integrated with mine-scale geological maps, geochemical and mineralogical information of gold deposits within the Allaqi-Heiani and Hodein areas. The results reveal the efficiency of spectral analysis techniques in delineation structural elements and geologic setting controlling the gold lodes. We conclude that gold metallogeny of the South Eastern Desert correlates with major post-accretionary shortening structures (~630-550 Ma), particularly the high–order splays that are associated with signs of concomitant magmatic or metasomatic activities. |
