PhD Thesis
Towards a high-resolution tomographic imaging of the lowermost mantle, IRAP, University of Toulouse III Paul Sabatier, November 5th 2012
Abstract: The D" layer is one of Earth's most heterogeneous location, hosting poorly understood features, which are most likely linked to the global dynamics of the mantle. Present days tomographic approaches cannot resolve correctly this area. The resolution of images from Earth's inner structure is strongly linked to precisely localizing earthquakes, and to have a good knowlegde of the frequency content of seismic waves. This thesis aims at building a global database of seismic traveltimes, data used for the development of tomographic images. Our method uses a more precise determination of the depths of earthquakes, allowing an improvement in measuring traveltimes. To a better evaluation of the frequency content, these measurements are performed in several frequency bands. A new approach for the computation of corrections to the complexity of the crust is presented as well. Finally, a preliminary imaging is presented, at regional and global scale, under the approximation of the ray theory, before a more complete description under Born approximation.
