Three-Dimensional Analysis of Geological Forms

Abstract

The requirements of a computerized modelling system for geological studies is described. The theory of many basic techniques is outlined and their advantages and limitations are discussed. Three examples are given of applications to geological data sets: the morphology of a [rhynchonellid] brachiopod after deformation, the structure of subsurface sand bodies and the local variability of cross-stratification in sandstones. In much of geology computerized modelling has considerable potential.
