Development of Fracture Analysis as Exploration Method

Abstract

ABSTRACT Fracture analysis is based on the premise that the earth’s crust is systematically fractured and that this fracturing can be recognized and analyzed on aerial photographs. This fracturing is due to external forces which have been active throughout geologic time. Four sets of fractures, arranged in two groups of two, the orientation of which is regionally systematic, have been found in all areas studied. The local deviations in the statistical mean direction of the fracture sets, when measured and analyzed, are found to be related to structure or stratigraphic anomalies.
