Identifying Prospective Areas for the Chatree Epithermal Gold Region from Airborne Magnetic Data Using Advanced Analyzing Techniques, with Interpretative Correlation

The Chatree Region, located in central Thailand, holds significant potential for gold exploration, hosting substantial mineral resources. The complex geological setting of this region, with its diverse lithologies and intricate structural controls, poses both significant opportunities and challenges for successful mineral exploration. Given these challenges, this study utilizes a geophysical approach focusing on magnetic data interpretation to enhance the precision and efficiency of identifying potential gold prospects.

Enhancements to the magnetic data were achieved through the application of Downward Continuation (DWC) and Automatic Gain Correction (AGC), which amplified near-surface features and improved signal clarity. Subsequently, by employing the Centre for Exploration Targeting (CET) Grid Analysis, zones of structural complexity, indicative of epithermal gold deposits were detected, which generated two heat maps, including Contact Occurrence Density (COD) and Orientation Entropy (OE). These maps revealed six major and seven minor potential gold prospect zones, providing a critical dataset for subsequent geological analysis. Geological correlations and lineament interpretation were then conducted to validate and refine the magnetic interpretations by integrating several filtered magnetic images with existing geological knowledge of the region. The results of this integrated approach show that many of the identified magnetic anomalies and lineaments correlate with known geology, highlighting the critical role of synthesizing advanced magnetic data analysis with geological expertise. This integration provides a valuable foundation for future exploration in the region and establishes an applicable methodological approach to other mineral exploration efforts.
