| 英文摘要 | Kutina et al. proposed the existence of a large fracture zone extending from northern China across the Yellow sea, Korean peninsula, East Sea (a. k. a., Sea of Japan) and on to Honshu Island, Japan, which they called the 'Forty-North Fracture Zone'. We investigated this proposed large tectonic feature from making large-scale regional gravity and magnetic anomaly maps by using GRACE and CHAMP satellite potential field data. The regional study area extended from 24 degrees to 56 degrees north latitude and 90 degrees E to 150 degrees E and the detailed area from 32 degrees N to 42 degrees N and 122 degrees E to 132 degrees E. Recently, Taylor et al. constructed the magnetic anomaly maps directly from CHAMP track data collected between June and December, 2005 after removing the core-generated and external fields from the measurements and then reduced these data to the pole to seek any tectonic features. They also produced a mathematical model using available geologic and geophysical information for their interpretation. In this study, we augmented a gravity anomaly field map from the GRACE data measured during a month of October, 2003. The measured potential differences data were converted to vertical gravity anomaly values using Gauss-Legendre quadrature method, and long wavelengths over 1100 km of the anomalies were removed by subtracting the latest EGM96 field to compare with the magnetic data. A curious latitudinal structure was found in both gravity and magnetic anomaly fields that showed an inverse correlation. 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. |
