Gravity modelling of the lower crust in Sardinia (Italy)

open access: yesAnnals of Geophysics, 1997
In this paper an example is given of an application of statistical techniques to the Bouguer anomalies analysis in order to design a simple crustal model using few a priori assumptions. All gravity measurements carried out in Sardinia have been collected

Correlation between the Bouguer gravity anomaly and the TAIGER tomography of the Taiwan region

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2018
The Bouguer gravity anomaly derived from observed gravity data and calculated from a 3-D P-wave velocity model were used to investigate the compatibility between the two to understand the crust structure of the Taiwan region.

A Study on the Compatibility of 3-D Seismic Velocity Structures with Gravity Data of Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2010
The Bouguer anomaly of Taiwan has been revised in this study based on more accurate terrain data provided by the Taiwanese Digital Terrain Model compiled by the Taiwan Forestry Bureau. Three seismic velocity models, those determined by Rau and Wu (1995),

Refining geoid and vertical gradient of gravity anomaly

open access: yesGeodesy and Geodynamics, 2011
We have derived and tested several relations between geoid (N) and quasi-geoid (ζ) with model validation. The elevation correction consists of the first-term (Bouguer anomaly) and second-term (vertical gradient of gravity anomaly).

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]

open access: yes, 2006
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...
