Ghaleh-Si prospect via exploratory data integration and proposing complementary exploration program Behnam mehdikhani b.mehdikhani@mi.iut.ac.ir 2009 Department of mining engineering Isfahan University of Technology , Isfahan 84156-83111, Iran Degree:M.Sc Language: Farsi Supervisor’s Name and Email address (10pt TNR-B) Ay-Ghaleh-Si lead-zinc deposit located in 24 Km southestern of Takab is one of the oldest mines in Iran operating since ancient time and is considered as an important archological site. The main objectives of current investigations were dafined to Determine the factors controling the Pb-Zn mineralization at Ay-Ghaleh-Si prospect via exploratory data integration such as geological, geochemical, mineralogical studies and propose complementary exploration program. The evailable exploratory data sets include the apparent resistivity, induced polarization, litogeochemical data and four drillhole logs data. An Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), with three visible and near infrared (VNIR) bands, six shortwave infrared (SWIR) bands and five thermal infrared (TIR) bands, was used to characterize alteration areas. Band ratio, principal compounent, least squre and spectral indices methods is used for alteration mapping that SI method has the best responces. So the Alunite and Kaolinite alteratione were mapped. Multivariate analysis of Stream geochemical samples determine the five capable area that old old pb-Zn mine was one of them. In order to achives drawn earlier the two geophysical data sets were inverted optimaly to recover three dimentional distribution of petrophysical properties of subsurface mineralization including true resistivity and chargability. In addition the geochemical samples were analysed by enzyme leach method. Fanaly based on 3D geophysical inverted modeles and topographic relief of the studied area and in order to check check the presence of probable subsurface mineralization driling one boreholes has been suggested.
