Abstract

The surface appearance and nature of lineaments showing on Landsat images are described, together with their likely causes. A computer model, based on the finite element method, is employed to show that the strain and stress effects over a deep underlying vertical fault are conducive to the development of two classes of faults, which are usually observed at the Earth's surface as lineaments. Some aspects of the involvement of these failure zones in mineral and petroleum prospecting, water supply and engineering geology are outlined.
