We investigate the use of Tikhonov regularization with the minimum support stabilizer for underdetermined 2-D inversion of gravity data. This stabilizer produces models with non-smooth properties which is useful for identifying geologic structures with ...

Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

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

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

3-D lithospheric structure and regional/residual Bouguer anomalies in the Arabia-Eurasia collision (Iran) [PDF]
The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia-Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components.
