An Approach to Moho Topography Recovery Using the On-Orbit GOCE Gravity Gradients and Its Applications in Tibet [PDF]

Remote Sensing, 2019
It is significant to determine the refined Moho topography for understanding the tectonic structure of the crust and upper mantle. A novel method to invert the Moho topography from the on-orbit gravity gradients is proposed in the present study. The Moho

Adaptive linear inversion of Moho topography in the Tibetan Plateau by combining gravity and seismic data

Frontiers in Earth Science
The Tibetan Plateau is a region where the Indian and Asian-European plates collide. A high-precision Moho topography model is important for the study of plate motion and internal tectonics of the Tibetan Plateau.

Determining the Moho topography using an improved inversion algorithm: a case study from the South China Sea

Frontiers in Earth Science
The Parker-Oldenburg method, as a classical frequency-domain algorithm, has been widely used in Moho topographic inversion. The method has two indispensable hyperparameters, which are the Moho density contrast and the average Moho depth.

Inversion of Moho topography in Taiwan using improved Parker-Oldenburg method

Frontiers in Earth Science
Taiwan is located at the junction between the Philippine Sea Plate and the Eurasian Plate, with intense tectonic movements in the region. A more accurate Moho topography model is significant for the study of the intrinsic genesis within Taiwan’s orogenic

Moho depth inferred from gravity and topography in an intraplate area (Iberian Chain) [PDF]

Tectonophysics, 2016
This paper discusses variations in Moho depth beneath an intraplate area, including the Iberian Chain thrust belt and the surrounding Cenozoic basins, based on topography and Bouguer anomaly data analysis. Two models of Moho depth mapping were used: Airy Moho depth maps and a Moho depth map derived from the Bouguer anomaly map.

Moho topography in the central Andes and its geodynamic implications

Earth and Planetary Science Letters, 2002
P-to-S converted waves at the continental Moho together with waves multiply reflected between the Earth’s surface and the Moho have been used to estimate the Moho depth and average crustal Vp/Vs variations in the central Andes. Our analysis confirms and significantly complements the Moho depth estimates previously obtained from wide-angle seismic ...

Moho topography beneath the Corinth Rift area (Greece) from inversion of gravity data [PDF]

Geophysical Journal International, 2001
International audienceOur aim is to understand better the rifting process by imaging the Moho depth variation beneath Corinth and Evvia. We present here the results of a gravity inversion analysis in the region of the Corinth and Evvia rift system, and ...

Three‐dimensional Moho topography in Italy: New constraints from receiver functions and controlled source seismology [PDF]

Geochemistry, Geophysics, Geosystems, 2011
In complex tectonics regions, seismological, geophysical, and geodynamic modeling require accurate definition of the Moho geometry. Various active and passive seismic experiments performed in the central Mediterranean region revealed local information on

Moho topography beneath the Iberian-Western Mediterranean region mapped from controlled-source and natural seismicity surveys

Tectonophysics, 2016
The complex tectonic interaction processes between the European and African plates at the Western Mediterranean have left marked imprints in the crustal architecture of this area, particularly concerning the lateral variations in crustal thicknesses. The detailed mapping of such variations is hence of large interest, as it provides a major constraint ...

New constraints on crustal structure and Moho topography in Central Tibet revealed by SinoProbe deep seismic reflection profiling

Tectonophysics, 2013
AbstractFrom October 2009 to May 2010, through the support of the SinoProbe project a series of deep seismic reflection profiles were conducted. In order to image deep crustal structure of central Tibet, these profiles extend from the northern Lhasa terrane to the Qiangtang terrane by crossing the Bangong–Nujiang suture (BNS).
