摘要
The authors investigated large tectonic feature of a large fracture zone called the ‘Forty-North Fracture Zone’ from making large-scale regional gravity and magnetic anomaly maps by using GRACE and CHAMP satellite potential field data. In this study, the authors augmented a gravity anomaly field map from the GRACE data measured during a month of October, 2003. A forward modeling was performed from using a spherical prism model and the wavenumber correlation analysis between these two anomaly fields was made to delineate the common features over the study area, and these results were discussed in relation to the existence of the ‘Forty-North Fracture Zone’ in the East Asian region.
