Abstract

Faults result from the initiation, growth and coalescence of individual fault segments. As a result (and as observed in a number of instances), faults may have internal branch lines. Creating 3D models of such faults with classical geomodeling methods is very cumbersome, in particular because of the intrinsic assumption that faults are manifold surfaces. In this paper, we propose an updated theoretical framework to represent such surfaces and propose a first implementation of a tangent fault branching operator that helps automating the generation of such surfaces. We apply this method to the modeling of a complex fault in the southern Corinth Gulf. In particular, we use it to test various ways of connecting two fault segments identified at the surface to a detachment at depth.
