Using the Satellaite Images for hydrothermal alteration mapping in Mokhtaran area; a case study from ?ANARAN Silver_ Gold indication

Abstract:
      The studied area, situated about 106km SW of Birjand, and is part of magmatic assemblage of the lut block. That mostly consists of andesite, dacite, latite and aglomerate. The intrusive rocks are micro-diorite.Hydrothermal alterations are kaolinitic, limonitic ? kaolinitic and silisic alterations, and are widespread in the area.
   This paper discusses, in detail, how to use image processing methods,especially used analysis of multivariate statistics to enhance and extract image information witch is relevant to hydrothermal processing including magmatic intrusion structures, structure and country Rocks hydrothermal alteration, ring structures and so an , and combained them with geological , geochemical and aeromagnetic Data. Finally hydrothermal Alteration zone and ANARAN Au_Ag hope- giving mining origins are introduced in MOKHTARAN sheet.
