A technique includes receiving seismic data indicative of a signal, which is produced by the interaction of reflection interfaces with a source wavelet. The reflection interfaces are associated with boundaries of a geological layer. The technique includes processing the seismic data to determine at least one slope change in the source wavelet caused by the interaction. The technique includes determining an attribute of the layer based at least in part on the determined slope change(s).
