A seismic section has been used as an effective material to investigate subsurface geological structures along the survey line. We can roughly understand the three-dimensional extension of geological structures when we arrange these seismic sections in geographical order. However, it is difficult to investigate developmental process of geological structures in a three-dimensioanl scale only from simple observations of the arranged sections. In this paper, we presented an outline of processing system for geological sections and showed examples of processed results for a simple test data. The system mainly includes functions to (1) digitize major reflection surfaces on seismic sections, (2) convert them into two-dimensional grid data, (3) illustrates graphically three-dimensional shapes of major reflected surfaces expressed by grid data.
Results processed by this system provide usefull data to investigate developmental process of geological structures and also can be used as original data for other analytical methods.
