Enhancing Zn-bearing gossans from GeoEye-1 and Landsat 8 OLI data for non-sulphide Zn deposit exploration

Multi-Sensor Satellite Remote-Sensing Data for Exploring Carbonate-Hosted Pb-Zn Mineralization: Akhlamad Area, Razavi Khorasan, North East Iran

“…The significant Pb-Zn metallogenic provinces in Iran, namely the Sanandaj-Sirjan zone, Central Iran zone, and Alborz zone, showed the age of host rock mineralization from upper Proterozoic to Oligocene-Miocene [44,45]. Some remote-sensing studies were conducted in the Gujer non-sulfide Zn deposit in the west of the Ravar city in Kerman, Pb-Zn SEDEX mineralization in the Behabad area in Central Iran, and carbonate-hosted Pb-Zn deposits in the Kashmar-Kerman tectonic zone, which confirmed the application of remote-sensing techniques for Pb-Zn exploration [12][13][14]26]. The study area selected in this investigation is located in the Binalud zone, Razavi Khorasan, NE Iran (Figure 1), which is a part of the Alborz collision belt.…”

“…Landsat-8 collects images for nine visible, nearinfrared (VNIR) and shortwave infrared (SWIR) bands (termed the Operational Land Imager (OLI)) and two long-wave thermal bands (named the Thermal Infrared Sensor (TIRS). The OLI images have been successfully utilized for many geological and mineral exploration studies [12][13][14][15][16][17][18][19][20]. The use of ASTER datasets for detecting alteration minerals has successfully continued owing to its broad coverage and unique integral bands, which are highly subtle to alteration minerals [21][22][23].…”
