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 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 ...

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.

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

Crustal thickness variations beneath Egypt through gravity inversion and forward modeling: linking surface thermal anomalies and Moho topography

Progress in Earth and Planetary Science
This study aims to quantify the topography of the Moho boundary, the lower crust and uppermost mantle contact of Egypt, in order to estimate the crustal thickness variation and its link to the distribution of thermal anomalies under Egypt.

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.

Effective elastic thickness in the Central Andes. Correlation to orogenic deformation styles and lower crust high-gravity anomaly [PDF]

, 2018
Global studies have assessed the importance of elastic thickness (Te) on orogenic evolution, showing that the style and nature of upper crustal shortening are influenced by the inherited lithospheric strength. Thus, pioneer works have identified that the

Moho Geometry Estimation Beneath the Gulf of Guinea From Satellite Gravity Data Based on a Regularized Non‐Linear Gravity Inversion

Earth and Space Science, 2023
In this work, we present a new gravimetric Moho model over the Gulf of Guinea computed from the inversion of the global gravity EIGEN‐6C4 model. The computation procedure contains a regularized non‐linear inversion algorithm.
