Gravity modelling of the lower crust in Sardinia (Italy)
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

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

The generalized Bouguer anomaly [PDF]
AbstractThis paper states on the new concept of the generalized Bouguer anomaly (GBA) that is defined upon the datum level of an arbitrary elevation. Discussions are particularly focused on how to realize the Bouguer anomaly that is free from the assumption of the Bouguer reduction densityρB, namely, theρB-free Bouguer anomaly, and on what is meant by ...

Spherical harmonic expansion is a commonly applied mathematical representation of the earth’s gravity field. This representation is implied by the potential coeffcients determined by using elements/parameters of the field observed on the surface of the ...

Bouguer anomaly map of New Zealand [PDF]
Summary The Bouguer map of New Zealand exhibits two major negative gravity anomalies. The Rangitikei‐Waiapu Anomaly, which intersects tne axial ranges of the North Island, indicates a crustal downwarp which is not in isostatic equilibrium.

Global geopotential models have not included the very high frequencies of the Earth’s external gravity field. This is called omission error. This omission error becomes more important in mountainous areas (areas with highly variable topography). The work

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