A Method for Estimation of Apparent Dips on Any Geological Section

Abstract

In this paper, we presented the principle and the BASIC program for numerical estimation of the apparent dips of bedding plapes ors an inclined surface (geological section) from dip-strike data obtained at irregularly spaced observation points (outcrops) . The presented program calculates apparellt dips on the sectional surface, which may be inclined at any angle, along the crossing line between the sectional surface and the horizontal Plane. The estimated apparent dips will be used as input data for Shiono et al. (1984a, b, c) 's programs in order to reconstract numerically the folding structure in the geological section.
