    • field of geological sciences

    • In this research, remote sensing and aeromagnetic data sets were integrated for the investigation of the structural features and alteration zones of the  mining area.
    • Using a sun-angle filter of the OLI data and, analytical signal and first-Order vertical derivative Techniques of aeromagnetic data, were detected two main lineaments with E-W and NW-SE trends in the study area.
  • The other lineaments with other trends in the study area are controlled by the same two major lineaments.
  • In this research, in order to identify alteration in the study area, the methods of band ratio in the ETM+ and OLI, false-color composite, relativ absorption band depth, and spectral angle mapping in the ASTER processing have been used .In total, using these methods, iron oxide, argillic, phillic, propylitic, and silicic alterations have been characterized in the study area.
  • This study also tried to study the aeromagnetic area’s response to different alteration regions by matching aeromagnetic anomalies with alteration zones.
  • Therefore, the alteration of iron oxide with negative magnetic anomalies, argillic and silicic alterations with positive anomalies of moderate to increasing magnetic anomalies, phillic alteration with moderate positive anomalies, and propylitic alteration have almost no direct correlation with magnetic field values.
    • Remote sensing data can be used to identification of the states, belts, and mineralization places, due to coverage of multi-temporal and multi-spectral of a wide area.
    • RS data are used for mineral exploration in two applications: (1) map geology and the faults and fractures that localize ore deposits; (2) recognize hydrothermally altered rocks by their spectral signatures.
    • Generally, remote sensing has an important role in the exploration of mineral deposits, lithological mapping, and detection of associated hydrothermal mineralizatio.Landsat 7 satellite is equipped with ETM+ sensor.
    • It was launched by NASA in 1999, which provides a ground survey in four modes.
