Abstract

Estimation of elastic anisotropy, which is usually caused by rock fabrics and mineral orientation, has an important role in exploration seismics and better understanding of crustal seismic reflections. If not properly taken care of during processing steps, it may lead to wrong interpretation or distorted seismic image. In this paper, a state-of-the-art under development Laser Doppler Interferometer (LDI) device is used to measure anisotropy of rock samples from a major deformation zone in the Bergslagen region in eastern Sweden. Results are then used to correct for the anisotropy effects using a non-hyperbolic moveout equation. The resulting stacked section shows partial improvement of the deformation zone compared with the isotropic processing section. This suggests that rock anisotropy may also contribute to generation of reflections from the deformation zones in the study area but requires further investigations.
