Description

An application (y-gRaph) to reconstruct paleostress fields from faults striations by means of the y–R diagram method is here presented. Based on modified Bott´s equation, the diagram relates y (azimuth of the maximum horizontal stress axis) and R (stress ratio) to a measured population of striated faults. Beyond the usual paleostress determination, this method is very useful when a variety of stress tensors is recorded within a fault population or to summarize the distribution and evolution of stress fields in a regional survey.
