Computer Processing of Geological Section (1)

in case that dip angle is constant vertically

Abstract

In this paper, we discussed the computerized method to draw a folding structure in a geological section based on the assumption that the dip angle is constant in the vertical direction. The assumption indicates the similar folding, and is different from the Busk's one of the parallel folding. If observed dip angles are interpolated linearly, we can express the forms of bedding planes by analytical functions. Further, if we have locational coordinates of the outcrops on a particular bedding plane, we can define the form of the bedding plane which passes through the outcrops. This method is simple in the mathematical treatise, and is suitable for computer processing more than the Busk method. We presented the BASIC program which draws one bedding plane on the screen of the personal computer, based on this method.
