Abstract
Rock strata may contain fine‐scale structures which are too small to be identified directly, but which can give rise to anomalous seismic reflection amplitudes. The variance caused by such anomalies severely hampers the use of reflection amplitudes for layer identification, and techniques are required which can identify or correct for the effects of such fine structure. We have done calculations which explore the consequences of two general structure types: wavy interfaces and very thin layers. In each case, a formalism is set up which enables us to identify systematically all of their effects. Computer modeling of realistic formations verified our calculations. We suggest that the strongly wavelength‐dependent response of such layers and their characteristic response waveforms may provide convenient tools for identifying fine‐scale features in strata.
