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

Landslides as natural phenomenon occur every year in many parts of the world, especially in hilly areas, andpose considerable life and property losses. Given the temperate and humid climate in northern Iran, most landslides occurred in this area are triggered due to rain. In this study, in order to predict the time and location of shallow landslides caused by rainfall, TRIGRS model was applied in Nekarood area in the Alborz mountain range in northern Iran and its sensitivity to a number of effective parameters in the landslide was assessed. After preparation of all required parameters, TRIGRS model wasimplemented to predict alandslide within the study area induced by a rainfall intensity of 1.27 mm/h lasting for 24 hours. The results showed that the model predicted landslides accurately. Also, the effect of rainfall duration on increasing the number of unstable cells isalso evident. In this regard, within the first hour, 0.19% of cells indicate a safety factor (FS) less than 1 while after 24 hoursit reaches 4.08%. To evaluate the model sensitivity to initial ground water level, some adjustments were made in the water table level. The result showed that, unlike the changes in precipitation, modelresponse to watertablefluctuation is not significant. Manuscript profile
