Numerical Descriptions of Busk's Graphical Method for Geological Section, and its BASIC Program

Abstract

According to the so-called Busk method, folding structures in geological sections can be reconstructed graphically by hand work. In this paper, the geometrical principles of the Busk method for drawing bedding planes were described in the manner of analytical geometry. The descriptions enable us to analyze folding structures numerically by computer without hand work. As an example, we presented the BASIC program which draws bedding planes automatically on the screen of the personal computer.
