Moho Beneath Tibet Based on a Joint Analysis of Gravity and Seismic Data

open access: yesGeochemistry, Geophysics, Geosystems, 2020
We use the improved Parker‐Oldenburg's formulas that include a reference depth into the exponential term and employ the Gauss‐fast Fourier transform method to determine Moho depth beneath the Tibetan Plateau.

Global crustal thickness from neural network inversion of surface wave data [PDF]

open access: yes, 2007
We present a neural network approach to invert surface wave data for a global model of crustal thickness with corresponding uncertainties. We model the a posteriori probability distribution of Moho depth as a mixture of Gaussians and let the various ...

Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

open access: yes, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼

Gravity-derived Moho map for Latvia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2020
A precise understanding of crustal structure is essential to the fields of geodynamics, seismology and certain branches of geophysics. A boundary between the crust and the mantle is known as the Mohorovičić discontinuity, simply referred to as the â ...

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]

open access: yes, 2017
The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

Moho Depths of Antarctica: Comparison of Seismic, Gravity, and Isostatic Results [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2019
AbstractThe lithospheric structure of Antarctica is still underexplored. Moho depth estimate studies are in disagreement by more than 10 km in several regions, including, for example, the hinterland of the Transantarctic Mountains. Taking account the sparseness of seismological stations and the nonuniqueness of potential field methods, inversions of ...

Depth determination of the Moho interface beneath the Tibetan plateau and other areas of China [PDF]

open access: yes, 2016
We apply the adaptive moving window method of Sun et al. to the most recent catalog data and the data recorded by portable stations to construct the velocity structure of the crust and upper mantle, and to determine the depth of the Moho interface ...

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

open access: yes, 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

open access: yesEarth 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.

Lateral variations in the crustal structure of the Indo-Eurasian collision zone [PDF]

open access: yes, 2018
We thank Michael Ritzwoller and two anonymous reviewers for constructive comments that have helped improve the manuscript. The majority of the seismic data used in this study were downloaded from IRIS DMC.
