Abstract
Dashkasan is one of the historical villages of East Azarbaijan province, located in the Shiramin village, part of the suburbs of Azarshahr, located south of Tabriz, the west of the Sahand volcano. In this paper, to investigate the increase in instability in the AzarShahr Dashkasan mineral region, tectonic studies have been conducted, based on field observations, the normal dashkasan fault has led to a displacement of 10 cm folding units at a height of 1373 meters above sea level. Therefore, the activation of tectonics is quite evident in terms of field observations. and with the adaptation of the results with the remote sensing map of the study area, it was determined that the most displacement, and by which stone was fractured, occurred along the normal sub-faults in the northwest-southeast. And considering that shear joints are also developed in the northwest, mines should also have abundant fractures in the central and southern parts of the Dashkasan region, so extracting and exploring this range is not correct, and in addition to the railroad, the tunnel and part of the main road are at risk of the normal active fault zone and slope instability. The density of mineral activity in the Dashkasan region is very high and necessary where the slope of the range is very steep, especially in mineral areas and abundant fractures that are adjacent to engineering projects such as tunnels and railway lines. There must be necessary measures for slope stabilization. Therefore, the activity of mining and exploration in the environment should not put people at risk.
