Application of gravity, magnetic and heat flow data to tectonic studies.

Session ID#: 78757

Session Description:
Satellite, terrestrial and marine observations of both gravity and magnetic fields, and heat flow measurements,  contribute to many studies, from imaging the Earth´s structure at all levels to modeling of geodynamic processes. Therefore, the determination of the density, magnetic and thermal structure of the lithosphere and upper mantle is critical for understanding of active tectonics. We invite presentations related to the processing and analysis of gravity, magnetic and heat flow data in terms of Earth models. 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 surface heat flow and potential fields; 4) Investigate isostatic models, deformations and stress concentration particularly as these relate to near-surface density anomalies and inherited structures.
