The paper reviews the seismic data processing techniques based on a ve
rsion of the Radon transform, developed for characterizing non-planar
and spatially limited structures of arbitrary orientations in crystall
ine rock. The examples are taken from the VSP surveys carried out in B
orehole KR6, at the Olkiluoto site in SW Finland, as a part of the Sit
e Investigation Programme for the final disposal of nuclear fuel, cond
ucted by Teollisuuden Voima Oy (TVO). Polarization analysis applied in
the transform space allows the positions of the reflectors to be dete
rmined by estimating the direction of the arrival of the reflected wav
es. The approach permits the determination of both the 3D-position and
local orientation of the observed reflectors. Anisotropic effects are
included and accounted for in the analysis.
