A method and associated apparatus for generating time slice maps and/or horizon maps, representative of an earth formation that is subject to seismic operation, in response to received seismic data includes the steps of: a) cross correlating a plurality of seismic traces from the data and a corresponding plurality of quadrature traces associated, respectively, with the plurality of seismic traces to obtain a corresponding plurality of cross correlation functions "Q(.tau.)", b) obtaining a plurality of particular values from the plurality of cross correlation functions "Q(.tau.)", and c) assigning the plurality of particular values to a respective plurality of reflection points on a map, each particular value being assigned to a different one of the reflection points, thereby constructing the time slice map. The particular value could be either a quadrature correlation coefficient (QCC), or a time lag (TL), or a sum of a normalized quadrature correlation coefficient and a normalized time lag (QCC n + TL n).
