Abstract

A graphical method for the analysis of the orientation of planar and linear structural elements in drill core is presented. Simple computation and projection operations applied to data taken from elements traced on the cylindrical surface of the core are required. To know a structural element(s) of reference, the method requires detailed structural analysis of the surface geology around the drill hole.
