Paper Number: SEG-2023-3900861
... (Chasseriau, 2003). Inversion of gravity and magnetic anomalies is widely used to obtain subsurface density and susceptibility structure (Parker, 1974; Last, 1983). The inversion results of gravity and magnetic anomalies are widely applicated in the exploration of crustal structure (Woollard, 1959), mining...

... that the normalization anomaly appears around 300 m in vertical components and 305 m in horizontal components. The pressure or fluid conditions in cluster 3 and cluster 1 are relatively similar, which means that the anomaly at 305 m in cluster 3 is likely not affected by pressure or fluid injection. As a comparison...

... We introduce a new idea to build a generalized training set for supervised machine learning (ML) methods aiming at gravity modelling. We build synthetic models reproducing only faults, which could be seen as the building blocks of each gravimetric anomaly. Here, we discuss preliminary results...

... We introduce a new filtering method for both detrending and local separation of potential field anomalies. The method is based on the modelling of a set of equivalent sources with the smallest possible volume, a sort of “atoms” selected among the many possible model that satisfy the potential...
