The depth distribution of azimuthal anisotropy in the continental upper mantle
Nature, 2007The most likely cause of seismic anisotropy in the Earth's upper mantle is the lattice preferred orientation of anisotropic minerals such as olivine. Its presence reflects dynamic processes related to formation of the lithosphere as well as to present-day tectonic motions.

Image-guided WEMVA for azimuthal anisotropy
SEG Technical Program Expanded Abstracts 2013, 2013Azimuthal anisotropy is common in layered basins with strong folding and fracturing effects. Traditional processing on individual azimuths usually yields images with inconsistent depths. In this paper, we propose to use an image obtained from one azimuth to constrain the image-space velocity analysis on other azimuths.

Observations of Azimuthal Anisotropy in Seismic Gathers
69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007D029 Observations of Azimuthal Anisotropy in Seismic Gathers D. Gray* (CGG Veritas) SUMMARY A method for displaying prestack seismic data that highlights azimuthal anisotropy is shown. Using this method to make observations of azimuthal anisotropy in prestack seismic data makes it clear that azimuthal anisotropy is observed in all types of seismic data

A New Fast Method to Measure Azimuthal Resistivity Anisotropy
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2001, 2001Apparent electric anisotropy can be estimated with an electrode configuration formed as the letter X. One electrode is placed at the end of each branch of the X and one is placed at about 1/3 of the distance from the center. Together with one electrode at the center, by the instrument, this makes a total of nine electrodes.

Azimuthal Anisotropy in ASCAT Backscatter Measurements
Bei Scatterometer-Beobachtungen der Landoberfläche der Erde wird der Rückstreukoeffizient (σ0) erheblich von der Abbildungsgeometrie des Satelliteninstruments beeinflusst, unter der die Messungen durchgeführt werden. Um geophysikalische Parameter wie die Bodenfeuchte genau bestimmen zu können, ist es wichtig, die Auswirkungen der azimutalen ...openaire +1 more source
