Abstract :

In recent years, application of remote sensing in mineral exploration had been developed and becoming an important tool. Most important capability of satellites in mining exploration is recognizing altered area. Because of close spatial relationship between mineral deposits and alteration, mineral mapping based of satellite data accelerate the exploration and reduce the cost. At Halakabad, the alteration zones are very broad and they are varied. Alteration zones are propylitic, argillic, advanced argillic and silicification. Using different methods highlighted altered area. Most Al-OH minerals like kaolinite, illite, pyrophyllite and alunite which are associated within argillic and advanced argillic zone were recognized by processing aster SWIR bands. Hydrothermal alteration zones in Halakabad are similar to Cu-Au high sulphidation. Alunite is an important mineral in advances argillic zone.
