Abstract: In potential field exploration, the Euler deconvolution method has been extensively utilized due to its minimal requirement for prior information. However, it yields significant dispersed results due to external interference. Based on a further investigation of the Euler deconvolution method, this study proposed a simple, effective finite-difference Euler deconvolution method for determining the depth and structural index of field sources. The proposed method leveraged the linear relationship between depth and structural index in the Euler equation. Combining data from multiple continuation heights at potential field source locations, a system of equations was constructed using the finite difference method to solve for coefficients, thereby determining the depth and structural index of field sources. The inversion was limited to potential horizontal locations of field sources, effectively reducing the number of inversion results. Additionally, the strategy of combining data from different heights for inversion mitigated the impacts of noise and other disturbances. Finally, the proposed method proved effective through model experiments and actual data.
