Spatial and Temporal Variations in Crustal Structure in the Eurasian Basin

Journal of Marine Science and Engineering, 2022
To understand the tectonic–magmatic history, crustal structure and crustal accretion mode of the Eurasian Basin in the Arctic, we calculated the crustal thickness, residual bathymetry (RB) and non-isostatic topography of the Eurasian Basin by using the ...

Future accreted terranes: a compilation of island arcs, oceanic plateaus, submarine ridges, seamounts, and continental fragments [PDF]

Solid Earth, 2014
Allochthonous accreted terranes are exotic geologic units that originated from anomalous crustal regions on a subducting oceanic plate and were transferred to the overriding plate by accretionary processes during subduction. The geographical regions that

Advances in Deformable Plate Tectonic Models: 1. Reconstructing Deformable Continental Blocks and Crustal Thicknesses Back Through Time

Geochemistry, Geophysics, Geosystems, 2022
Deformable plate tectonic models have been demonstrated to be a useful technique for quantifying temporal variations in strain rate and crustal thickness within recent plate kinematic studies.

Crustal thickness variations in northern Morocco [PDF]

Journal of Geophysical Research: Solid Earth, 2012
During the TopoIberia experiment, a total of 26 seismic broadband stations were recording in northern Morocco, providing for the first time extended regional coverage for investigating structure and seismotectonics of the southern branch of the Betic‐Rif arc, its foreland, and the Atlas domain.

Variation in thermal structure with crustal thickness for the crust beneath the Peninsular Malaysia

Journal of Asian Earth Sciences: X, 2023
We present a regional thermal structure as well as a new crustal thickness model beneath the Peninsular Malaysia and the surrounding regions. Curie point depth estimates for the entire area range between ∼ 17 – 46 km with a mean of 29 km.

Qinghai-Tibet Plateau crustal thickness derived from EGM2008 and CRSUT2.0

Geodesy and Geodynamics, 2014
Qinghai-Tibet Plateau is the most complex region for crustal thickness inversion, while high-resolution earth gravity model (EGM) makes it possible to obtain high precision gravity anomaly, which is a key parameter to depict the Earth’s inner structure ...

Deformation and exhumation in thick continental crusts induced by valley incision of elevated plateaux [PDF]

Solid Earth
Surface processes such as erosion and sedimentation play a critical role in crustal deformation, particularly in actively deforming orogenic belts. While these processes have been extensively studied in large-scale erosive and tectonically active regions,

Crustal thickness beneath Rio de Janeiro, Brazil, from spectra of SH waves at station RDJ [PDF]

Geofísica Internacional, 2006
Amplitude and phase spectra of long period analog S wave records were used to estimate crustal thickness under Rio de Janeiro seismic station. Earthquakes with shallow focal depths (10-33 km) and epicentral distances varying from 83 to 88 degrees ...

Satellite magnetic anomalies of the Antarctic crust

Annals of Geophysics, 2000
Spatially and temporally static crustal magnetic anomalies are contaminated by static core field effects above spherical harmonic degree 12 and dynamic, large-amplitude external fields.
