Abstract
This paper presents a computer-aided method for analysing geological cross sections in compressive terranes. The deformation of thrust sheets is simulated using the geometrical model of fault-bend folding. The modelling focuses on complex thrust configurations like multiple imbrications and duplexes. This paper discusses the geometrical constraints of the fault-bend fold model to highlight the applicability and methodology of the kinematic reconstruction method. An application to a section from the Jura Mountains shows that complex thrust geometries can be analysed. Improvements on earlier work concern the treatment of transported piggy-back thrust sheets and the introduction of sedimentation and erosion processes. With the current computer method it is possible to investigate the stratigraphie patterns that develop in the syn-orogenic basins. This can provide insight in understanding the kinematic evolution of thrust systems.
