6:181-198. The fine-layering of the eadh's subsu ace causes appaÍent amplitude-versus-angle (AVA) effects in seismic reflection data- One can distinguish between propagation- and Íeflection-related apparent AVA effects: propagation through finely layered media causes angle-dependent wavelet díspercion, wheÍeas the Íeflection of a package of thin layers is accompanied by angle-dependent wavelel ínteíerence. Obviously, both types of apparent AVA effects hamper AVA inversion for the medium parameters. In migration, the pÍopagation-related dispersion effects can be compensated for in the downwaÍd extrapolation process by means of inverse geneÍalized p.imary propagators. The reflection-related inteÍference effects can be equalized for all propagation angles by applying an angle-dependent filter in the iÍnaging step. Angle-dependent migration, including the above-mentioned modifications, yields an angle-dependent reflectivity section in which the apparent AVA effects of fine-layering are suppressed. This type of section may serve as inpu! for local AvA inversion as well as for multiscale characterization by meanN of the wavelet ttansfoÍm. The latter process yields information about the local scaling exponents of composite reflectors in the eaÍth's subsurface
