Papua New Guinea Moho inversion based on XGM 2019e gravity field model
Frontiers in Earth Science, 2023 The construction of the high-resolution Moho depth model is significant for studying the characteristics of the complex tectonic movement (seafloor spreading, plate subduction phenomena) in Papua New Guinea.

重力異常データのカラムインバージョンから見積もったモホ不連続面の形状 [PDF]
, 2004 We present an inversion method, called "column inversion", to retrieve two-dimensional variation of the depth to the Moho discontinuity from Bouguer gravity anomaly data, assuming that a density jump between the lower crust and upper mantle is regionally

Moho Beneath Tibet Based on a Joint Analysis of Gravity and Seismic Data
Geochemistry, 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]
, 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 ...

Seismic wide-angle study of accreted Proterozoic crust in southeastern Wyoming [PDF]
, 1994 A seismic wide-angle xperiment was conducted in southeastern Wyoming, USA to investigate the seismic character of a postulated Proterozoic magmatic arc south of the suture (Cheyenne Belt) to the Archean Wyoming Province.

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

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

Gravity-derived Moho map for Latvia [PDF]
Estonian 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 MohoroviÄiÄ discontinuity, simply referred to as the â ...

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