This study focuses on the analysis of airborne magnetic data to identify surface and subsurface structures at various depths within the GolGohar mining area. The GolGohar region is recognized as one of the active mining areas in Iran, comprising six major anomalies along with several minor anomalies that contribute to significant complexities in its geological structures. Despite numerous studies conducted in this area, its deeper structures have not been thoroughly examined.
The methodology of this research begins with the application of the Reduced to the Pole (RTP) filter, utilizing Fast Fourier Transform (FFT) techniques to distinguish local residual structures from broader regional features. This multiscale approach facilitates a deeper understanding of the geological complexities within the study area and clearly reveals its subsurface structures. Subsequently, advanced geophysical methods such as Total Horizontal Derivative (TDHR) and Tilt Angle Derivative (TDR) are employed to delineate the boundaries of anomalies. The objective of employing these methods is to delineate the structural boundaries of magnetic anomalies. Additionally, an advanced method for estimating the depth of magnetic anomalies, known as Euler Deconvolution, has been employed. The primary objective of this method is to determine the depths of both surface and subsurface magnetic structures.
Interpretations derived from the airborne magnetic data indicate that the geological structures generally trend NW-SE and are disrupted and offset by a series of faults with an approximately N-S orientation. Furthermore, the results suggest that ferromagnetic bodies are situated at considerable depths, extending from the NW towards the SE. This study is particularly important for identifying the magnetic anomaly structures in the GolGohar mining area, as it not only reveals the concealed anomalies of this mineral-rich region but also clarifies the arrangement of these anomalies effectively.
