An aeromagnetic denoising-decomposition-3D inversion approach for mineral exploration

Reduction of aeromagnetic noise and extraction mineralization-related residual anomalies are critical for data processing in mineral exploration. This study introduced a multifractal singular value decomposition (MSVD) method to remove the improved bi-dimensional empirical mode (BEMD) algorithm extract magnetic anomalies. It is shown that MSVD BEMD could effectively reduce Then, wavenumber–domain iterative approach applied 3D imaging gradients with depth constraints, which rapid tool qualitative quantitative interpretation suitable rapidly large-scale data. The inversion result verified by four geological sections along regional tectonic directions some drilling holes on deposits. revealed this proposed practical effective dealing
