The 3D simulation of coupled backward and forward deformation of geological layers is a new step in basin modelling. Although this problem could be addressed with either mechanical or kinematic approaches, the mechanical approach remains too complex to be addressed properly. The kinematic model described here allows a geologically valid path, which takes into account an incremental evolution in time. To obtain a better description of 3D geometries, the model uses a full hexaedric discretization and the discrete neutral surface of each layer is used when performing the flexural slip deformation. An application to a synthetic geological case is then proposed, to study the behaviour of the structure in compressional and extensional contexts.

New Insights into Structural Interpretation and Modelling
This title has arisen from the Geological Society of London conference of the same name. Since the publication of the predecessor of this book (‘Modern insights into structural interpretation, validation and modelling’, SP99, 1996, edited by Buchanan & Nieuwland) much progress has been made. This has been primarily thanks to the continuously increasing computing speed and computer memory capacity, which has positively affected all fields in structural interpretation, seismics and modelling, directly or indirectly.
‘New insights in structural interpretation and modelling’, presents a balanced overview of what the title promises. It is intended as a book that will serve the experienced professional as well as more advanced students in earth sciences, with a broad selection of topics ranging from classical field based studies to state of the art analogue and numerical modeling. The leaders of their fields have written some of the chapters, whereas younger authors with a fresh outlook and new ideas have written other chapters.
