Abstract :

Abstract Background and Objective: The impact of tectonic activities on environmental pollution was investigated by lead and zinc mines at Surmeh. Method: In this study, the 6EPA standard method was used and tested 7 times around the water and soil around the area and was expected to have adverse environmental effects, like other lead and zinc mines in the country such as Angoran and Zahabad. Finding: Studies have shown that the amount of lead in soil and water is standard for agricultural use and has little environmental impact. Discussion and Conclusion: Based on stratigraphic columns prepared in the Surmeh Mountains containing the salt marshes of the Hormoz and calcareous Dalan Formations and the Nare Evaporites, the tectonic effects of alpine activity acting in two tensile-shear and compressional conditions have resulted in the Dalan calcareous formation containing ore deposits. Lead and some clay minerals are marl, located in the core of the Surma anticline which provides salt diapirism conditions in different tectonic phases and eventually due to the calcium carbonate uptake in the Dalan Formation and the high uptake capacity of clay and salt minerals in the lead. Higher levels prevent lead release in groundwater and its derivatives in confined air and soil. Thus it can be said that the regional tectonics has resulted in the creation of a natural filter for active adsorption of lead in the range.
