“…A multi-technique approach involving the use of XRF results was used by de Oliveira et al 160 to develop a detailed model of the bauxite deposit of Barro Alto, Central Brazil describing the evolution of eight different facies. Pazand et al 161 used the XRF technique (for the majors) and ICP-MS (for the traces) to prepare a distribution map of lithogeochemical and alteration indices for the copper mineralisation in the Sonajil area, Northwest Iran. The distribution map was based on 1248 sampling squares, each 100 Â 100 m 2 extending over this hydrothermally altered Cu mineralised area.…”

“…The Savalan volcano is ca 100 km to the NW of Tabriz and the Sahand volcano is located ca 40 km south of Tabriz city [27]. Hydrogeochemical processes and chemical characteristics around Sahand Mountain indicate it is structurally part of the northern UDMA [28] which has been found to contain zeolites [29][30][31]. The high calcic-alkaline -SiO2 conditions in all parts of the Sahand and Sabalan facilitate zeolite formation [25,32].…”

“…Zeolites in Iran have been found in association with certain types of mineralization that involve the formation of copper [28]; bentionitic clays (zeolitic-bentonitic sequences have been found in the province of Tabriz); borates (borate deposits in Iran may be associated with zeolite deposits since those formed in other parts of the world under similar conditions do contain zeolitic mineralizations. ); mercury (some of the mined mercury deposits occur in hydrothermal areas also associated with zeolite formation.…”

Background:The Kandovan region in Iran is physically and geologically similar to the Cappadocian region in Turkey where fibrous zeolites, including erionite, have been found in volcanic tuffs. In some Cappodocian villages there is strong evidence that erionite, and possibly related minerals, are responsible for the high level of mesothelioma found there. So, although mesothelioma clusters have not been reported in Kandovan, it is a plausible hypothesis that many cases of mesothelioma in Iran may be due to naturally occurring fibrous zeolites.Methods: A detailed study of Iranian geology was made to determine similarities between the Kandovan region and Cappadocia, ‘inter-mountain zones’ in the Western US and Mexico. Areas where mesothelioma cases probably attributable to erionite exposure have been found. Results:Although there is a long history of asbestos use in Iran many cases of mesothelioma do not present with positive asbestos exposure histories. Since fibrous zeolites are so widespread, why have not more mesotheliomas attributable to them been found throughout Iran? Various possible reasons were explored including misdiagnosis, poor surveillance, a general lack of awareness that this tumor may be linked to mineral fibre exposure. There is also the analytical problem of identifying fibrous erionite in lung tissue.Conclusions:There is every reason to believe mesotheliomas due to fibrous zeolite including erionite will be found in Iran. The most likely places to find them are the villages that look very similar to those found in Cappadocia since these are based upon similar geological formations.

Main purpose of this research is to present a local scale GIS-based mineral prospectivity model for prospecting Cu porphyry mineralization, and to validate the produced model by field observation, surface sampling and drilling data. Sonajeel area which is the subject of this study is a part of Arasbaran mineralization belt, NW of Iran.Constructing a mathematical exploratory algorithm based on a mineralization type is a complicated and interdisciplinary task. For this purpose, results from processing and interpreting different data sets including geology, geochemistry and remote sensing were considered. A comprehensive exploratory integration model was built up considering the exploration stage and the descriptive porphyry mineralization model suggested by Sillitoe, 2010. In order to prepare inputs for GIS-based exploration model, value assigned grids or evidence layers were produced using fuzzy membership curves and then integrated via gamma fuzzy function. In addition, for defuzzification and prioritizing the mineral prospectivity map, a Concentration-Area (C-A) fractal model was applied on the pixel values of the prospectivity map. Finally, the results were confirmed via field observation, surface sampling and drilling. Borehole logs at the first priority displayed a Cu mineralization zone with an average grade of 0.5%.
