TL;DR: In this paper, the authors compare the results of the application of the methode selective developpee and methode standard on the bandes 1, 4, 5, 6, 7 and 8 of the Landsat TM.
Abstract: RESUMELa methode d'analyse en composantes principales est utilisee couramment pour la cartographie des alterations dans les provinces metallogeniques. Trois techniques d'analyse en composantes principales sont utilisees pour la cartographie des alterations autour d'intrusions porphyriques dans la zone de Meiduk: la methode selective, la methode selective developpee ou Crosta et la methode standard. Dans cette etude, on compare les resultats de l'application de ces trois techniques differentes sur les bandes Landsat TM. La comparaison est basee principalement sur l'analyse visuelle et les observations des resultats sur le terrain. L'analyse en composantes principales selective utilisant les bandes 5 et 7 de TM est la plus adequate pour la cartographie des alterations. Toutefois, les zones vegetales sont aussi mises en evidence dans l'image PC2. L'application de la methode selective developpee sur les bandes 1, 4, 5 et 7 de TM pour la cartographie des hydroxyles met en evidence des halos d'alteration autour...

TL;DR: In this paper, a variety of spatial geological data were compiled, evaluated and integrated to produce a potential map for porphyry copper deposits in the northern Shahr e Babak, Iran, within a total area of approximately 408 km2.
Abstract: A variety of spatial geological data were compiled, evaluated and integrated to produce a potential map for porphyry copper deposits in the northern Shahr e Babak, Iran, within a total area of approximately 408 km2. Remotely sensed data including LANDSAT Thematic Mapper were used to create the hydrothermal alteration haloes around intrusive bodies. Geological data, such as exposed granitic to intermediate intrusions, and part of the lineaments were extracted from available geological maps. Aeromagnetic data were also used to extract magnetic anomalies and extra lineaments. The Conditional Independence test was carried out on five binary maps representing diagnostic deposit recognition criteria, and four of them were then integrated using a weights of evidence model. The procedure generated a posterior probability map identifying favourable areas for porphyry copper deposits. The final map highlights the most important known copper deposits in high favourability domains. Some new target areas are also loca...

TL;DR: In this paper, a conceptual model for water circulation is presented, where the authors show that the high water temperature is due mainly to circulation of the water in deep faults in a pull-apart basin northwest of the Gisakan anticline, and also to exothermic reactions.
Abstract: Combined geological, hydrological and hydrochemical studies and geothermometry of the Dalaki thermal springs on the margin of the Zagros Mountains, Iran, indicate that the source of the spring water is meteoric water, contaminated by oilfield brine and evaporites. The high water temperature is due mainly to circulation of the water in deep faults in a pull-apart basin northwest of the Gisakan anticline, and also to exothermic reactions. Contamination of the water also occurs in the pull-apart basin. Drilling wells in the karstic up-flow side of the Rahdar fault may help to avoid the contaminated water and have a major effect on water resource management in the area. A conceptual model for water circulation is presented.
