Abstract In this paper, we use a robust inversion algorithm, which have tested in many regional studies, to obtain the first global model of Curie-point depth (GCDM) from magnetic anomaly based on fractal magnetization. Statistically, oceanic Curie mean is smaller than continental one, but depths are almost bimodal, showing shallow points some old cratons. Oceanic show modifications by hydrothermal circulations young lithosphere and thermal perturbations lithosphere. also strong dependence...
Integrated Ocean Drilling Program (IODP) Expedition 316 Sites C0006 and C0007 examined the deformation front of Nankai accretionary prism offshore Kii Peninsula, Japan. In drilling area, frontal thrust shows unusual behavior as compared to other regions Trough. results, integrated with observations from seismic reflection profiles, suggest that has been active since ∼0.78–0.436 Ma accommodated ∼13 34% estimated plate convergence during time. The remainder likely distributed among...
We have investigated Mesozoic geological problems around the South China Sea (SCS) based on gravimetric, magnetic, seismic, and lithofacies data. Three-dimensional analytical signal amplitudes (ASA) of magnetic anomalies clearly define inland tectonic boundaries residual basins offshore. The ASA suggest that degree magmatism and/or average susceptibility igneous rocks increase southeastwards late-stage A-type present along coast southeast possess highest effective susceptibility. geophysical...
In hydrocarbon exploration, seismic data collected in the field inevitably encounters noise interference, which subsequently affects processing and interpretation. Recently, deep learning methods have gained widespread popularity denoising. Among these methods, U-Net has shown some potential, but its performance complex suppression needs further improvement due to limitations of structure. Moreover, majority existing primarily focus on synthetic noises with single characteristics, such as...
The depths to the magnetic layer bottom (Zb) in South China Sea (SCS) area are estimated by computing radially averaged amplitude spectra of total field anomalies. We test different sizes moving windows which calculated better understand how window affect depth estimations. Apart from lowering resolutions Zb, larger do not necessarily incur presumable increases Zb SCS area. Although centroid method is taken as our primary technique for estimating cross check, spectral peak and non-linear...
Using recently published global magnetic models, we present the first independent constraint on North Atlantic geothermal state and mantle dynamics from anomaly inversion with a fractal magnetization model. Two theoretical models of radial amplitude spectrum anomalies are found almost identical, both applicable to detecting Curie depths in using centroid method based spectral linearization at certain wave number bands. Theoretical numerical studies confirm robustness this scheme. A exponent...
Abstract In 2016, we carried out a coincidental multichannel reflection seismic and wide‐angle reflection/refraction experiment along 320‐km‐long profile across the northeastern margin of South China Sea. Based on these new data, studied velocity structure transitional continental crust using both forward modeling travel‐time tomography. The model shows that Mesozoic sediments have velocities 4.3–5.3 km/s are about 3–6 km thick in magnetically quiet Chaoshan Depression attenuated crust....
SUMMARY Density is an important parameter for both geological research and geophysical exploration. However, model-driven seismic inversion methods, high-fidelity density challenging due to wave traveltime insensitivity crosstalk that has with velocity. To circumvent the challenge of inversion, some methods treat as a constant value or derive from velocity through empirical equation. On other hand, deep learning approaches are completely driven by data have strong target-oriented...
Earth’s tectonic history is punctuated by several cycles of supercontinent assembly and breakup that profoundly influenced the lithospheric structure; however, roles various factors controlling continental strength deformation during remain debated. The effective elastic thickness (Te) reflects lithosphere’s long-term, depth-integrated useful for deciphering complex evolution continents. In this study, we estimate a new global map Te projected onto  grid...
Along-strike heterogeneity of pre-existing Mesozoic structures have caused different rift-to-drift features from east to west the South China Sea (SCS). The southwestern margins undergone prolonged extension and propagating seafloor spreading, leading crustal significantly northeastern SCS margin. geodynamic mechanism termination spreading in is still enigmatic.In this study, we present a ~780 km long P-wave velocity model across two conjugate continental oceanic basin at tip wide-angle...
SUMMARY The post-spreading magmatic activities in the northeastern South China Sea (SCS) margin are very strong, evidenced by widely distributed high-velocity lower crust (HVLC) and numerous volcanoes. However, there large contrasts crustal structure between Southern Depression (TSD) of Tainan Basin volcanic continental slope area further south. We analyse their P-wave velocity structures based on a newly acquired wide-angle ocean bottom seismic data set. Cenozoic strata below TSD, failed...
Abstract Macrostructures preserved in deformed rocks are essential for the understanding of their evolution, especially when deformation is weak and hard to discriminate regional scale or purely through geophysical data. In order resolve inconsistency between NS trending fracture zones NE oriented spreading fabrics South China Sea during latest stage, we analyzed macrostructures identifiable from basalt consolidated sediment samples Integrated Ocean Drilling Program (IODP) Sites U1431 U1433....
