Abstract

Gonharan district is located 26 km east of Daran city in the Sanandaj-Sirjan area and in the Melair-Isfahan metallurgical belt.From the structural point of view, the main fold consists of an anticline with a WNW-ESE trend and an axial inclination towards the ESE and close to its plunge location. A secondary fault with a northwest-southeast trend is also located in the south of the range. The slope of low layers and layering levels in the Lower Cretaceous rock-layer units shows the main concentration with a slight slope towards the ESE (105/16) approximately parallel to the Chinese axis. The faults collected in the study area are divided into four categories according to the direction and mechanism of movement, the category of reverse to transpressional faults with a WNW-ESE direction and a slope towards the NNE with a maximum concentration of ten percent in 50.020 is statistically the most abundant category of the faults are limited. The rock units in the area include limestone and lower Cretaceous marl in the Aptian-Albian scub and Quaternary sediments.Gray limestone with orbitulin in the lower part hosts most of the mineral matter, and marl and clay limestone are placed on it in a continuous and even slope.The mineralized dolomitized sections are mostly related to the reverse fault zones and have a tendency to be approximately parallel to the reverse faults and fracture faces.The dolomitized parts are brittle and brittle, and most of their mineral veins are approximately parallel to the tensile sheets and normal faults.
