Abstarct: This study aims to explore fluorite and zinc deposits in the western Tuyé-Damghan region using geophysical methods, specifically magnetometry and gravimetry. This area is of high economic significance due to its diverse geological structures and mineral deposit potential. In this research, 305 magnetic data measurement points were recorded at 10-meter intervals, along with 150 gravity measurement points. After applying standard geophysical corrections, data analysis was conducted using various filters such as tilt angle, gradient, reduction to the pole, and gravity depth gradient analysis. The results of magnetic data processing identified the boundaries of magnetic anomalies and subsurface structures associated with mineral deposits. The analysis of magnetic anomalies showed that, with upward field continuation, small and shallow anomalies weakened, while deeper anomalies remained stable at elevations of 30 to 50 meters, indicating the deep concentration of fluorite and zinc minerals. In the downward continuation of the field, high-intensity anomalies were identified at depths of 5 to 15 meters, marking shallow mineral resources. Additionally, the analysis of gravity data helped identify areas with higher density, which are likely to host fluorite and zinc mineralization. Variations in the depth gradient of gravity data indicated that regions with higher density overlapped with high-intensity magnetic regions, further confirming the possible presence of mineral deposits at the identified depths. Furthermore, the application of the tilt angle filter demonstrated that areas with sharp and distinct boundaries are likely to contain mineral accumulations. baxsed on these findings, regions where strong magnetic and gravity anomalies exist near major and minor faults, with increasing anomaly intensity at greater depths, were identified as primary drilling targets, while areas with weaker but continuous anomalies were proposed as secondary drilling sites. Overall, this study successfully combined magnetometry and gravimetry to accurately identify potential drilling zones, and its results can contribute to cost reduction and optimization of exploration operations.
