  The Behabad region is located within a tectono–sedimentary zone in southeast Yazd province, Central Iran. The tectonic activities have deformed and faulted the Mesozoic and Quaternary formations in this area. The faults in Kuhbanan and Behabad have played a key role in the evolution of geological events, mineralization, and the formation of Behabad–Kuhbanan horst. These faults have separated the Posht-e-Badam block from the Tabas block and the Behabad zone from the Abdoghi–Ravar tectonic zone, respectively. Remote-sensing techniques and field observations show that the Pb–Zn veins share similar trends with the structures. The compressional system induced by the activities of the Behabad-1 and 2 fault systems have caused the formation of thrusts, drag, and sigmoidal folds, the North Behabad horst, and shear zones containing Pb–Zn mineralization. The Mississippi Valley-type (MVT) deposits and strata band mineralization types are present in the study area. In terms of the temporal phase controller, it is consistent with the tectonic-magmatic model of the Late Paleozoic–Triassic period; in terms of the spatial controller, mineralization is situated in the tectonic–metallogeny province of Central Iran and the ore deposits that mainly follow the geometry of the thrust faults’ crushed zones. The thrust fault that drives the dolomite unit over the limestone is the main cause of the ore solutions migration. According to the MVT mineralization and the correlation between structures and mineralization, the sulfide deposits can be potentially found at the base of the Permo–Triassic units in the studied area. There are several active and non-active Zn–Pb mines such as Abheydar, Rikalaghi, and Tapesorkh. Manuscript profile

  Base-metals sulfide mineralization in Galena and sphalerite forms with little amount of pyrite, in Mobarak andElika formation have been occurred in the studied region. Chemically, all deposit phases have compositinghemogen region. Mineralization has been followed the fault general process in the region, and the main texturesin the ore are vein texture and open space filing. Genetically, studied deposits are epigenetic. Field featuresessentially have resulted mineralogical investigations and geochemical surveys on trace elements and rare earthelements (REE), they have included ore metals source in sulfide Pb-Zn mineralization in Kelardasht regionshowed carbonate - hosted mineralized rocks (upper Paleozoic , lower Triassic ) in deposit. In genetic relationbetween Pb-Zn mineralization in this deposit with Akapol monzonit quartz - monzodiorite intrusion (aged toupper Eocene - lower Paleocene), Were located near to studied Pb-Zn deposits, Akapol intrusion have played asrequired heating source that heated ore fluids. According to Eu negative anomalies in ore and host rock samples,and were seemed The source of hydrothermal fluids in the studied region have been the surface and atmosphericfull - oxygen water (meteoric) have been warm through closing Akapol intrusion and have been solved theelements and then have been deposited them in the host rock fault crushes, cracks and joints, and then circulationin base-metals have enriched carbonate hosted units.
