ENERGY HISTOGRAMS FOR THE CHARACTERIZATION OF DEEP REFLECTION SEISMIC PROFILES

We modified Dohr's method and were able to establish trends of crustal reflectivity distribution. Four main types of crustal reflectivity-depth histograms could be distinguished. Dohr's method was based on line drawings from which the total length of reflections was calculated for time-distance frames along the profile. In this paper we present a new method to derive such histograms automatically from the final stack tapes. This allows an objective comparison of deep reflection seismograms from different crustal units and from different research groups. It is shown that our energy histograms are consistent with earlier manually produced histograms and that the previous results can be reproduced. First applications to DEKORP and KTB data in Germany are presented.
