عنوان انگلیسی A novel method for interpreting potential field anomalies using the Rootsig function
چکیده انگلیسی مقاله Potential field data play a crucial role in the interpretation of various geological structural features. The application of edge detection techniques significantly improves the capacity to delineate subsurface structures. In recent years, a variety of methodologies have been developed to identify edges; however, each of these methodologies possesses distinct advantages and limitations. This study presents a novel edge enhancement technique that employs the Total Horizontal Derivative (THD) in conjunction with the Rootsig activation function (RTHD). This technique is applied to the interpretation of potential field data to enhance structural mapping. The effectiveness of the RTHD is evaluated through the interpretation of synthetic gravity and magnetic anomalies, both with and without the presence of noise, including sources located at various depths. Furthermore, the RTHD technique is applied to investigate gravity field data from the Považský Inovec Mountains, located in the Western Carpathians of Slovakia. In this region, the boundaries of the primary anomalies, as well as the Považie and Ripňany faults, are distinctly delineated. The results demonstrate that the RTHD approach effectively delineates edges and balances the amplitudes of both shallow and deep-seated sources, in contrast to traditional edge enhancement methods. The findings indicate that the RTHD represents a more effective strategy for structural mapping when utilizing gravity and magnetic data.
