DI51B:
Gravity and Magnetic Field Models and Their Application to Tectonics II Posters


Session ID#: 10236

Session Description:
Satellite, terrestrial and marine observations of both gravity and magnetic fields contribute to a wide range of studies: from imaging the Earth´s structure at all levels to modeling of geodynamic processes.  Therefore, the determination of the density and magnetic structure of the lithosphere and upper mantle is critical for understanding of active tectonics. We invite presentations related to spatial and temporal variations of the Earth gravity and magnetic field: from preparation of the initial models to their interpretation within various geophysical applications. In particularly we encourage contributions that: 1) Develop new methods for the construction of integrative physical models; 2) Present models of the lithosphere and mantle based on joint interpretation of different geophysical data sets; 3) Determine the factors, such as temperature and composition, that are reflected in potential fields; 4) Investigate isostatic models, deformations and stress concentration particularly as these relate to near-surface density anomalies and inherited structures.
