| The south Zagros Suture Zone (ZSZ) is located in the Northern Eastern part of Kurdistan region-Iraq and known as volcano-tectonic area. It is characterized by its potential iron resources. In this study, we attempt to delineate the subsurface structures using integrated interpretation of existing magnetic and available geological data. The land magnetic survey of the area under study is about (3.5 * 2.5) ≈ 8.75 km2. The total number of magnetic stations was up to 680 and the average distribution of stations was approximately 85 stations per km2. Interpretation of analytical signal and horizontal gradient of the magnetic data indicated that the area is characterized by the existence of high gradient magnetic anomalies associated with existing iron mineralization and manifestations. Horizontal gradient analysis also enabled tracing several subsurface geological structures (iron mineralization zone) are trending NE-SW and have extensions more than 2.0 km. The 3-D Euler deconvolution and 2-D Power Spectrum methods have been applied to the magnetic data and provided fast information about both the depth and trends of the shallower subsurface structures in the area. The depths of iron deposits vary from 150 to 300 m with average 225 m. according to these magnetic measurements (680 stations only). The preliminary estimation of the iron bodies in the region is about 125 million tonnes | ||
