The use of 4500 km2 of amalgamated 3D seismic surveys allowed for an improved intra-Carboniferous seismic interpretation of the Dutch Cleaver Bank High, which is part of the Southern North Sea Carboniferous Basin. The observations of faults that were active during the Late Carboniferous are reviewed in the context of what is described in literature about the regional structural framework of the basin. The high quality seismic data show at least three distinct fault trends, namely east-west, NE—SW and NW—SE, active before Rotliegend times. All of these trends are inherited from older existing zones of weakness, and furthermore, all three trends have been reactivated again during the Mesozoic or Cenozoic to some extent. The interpretation of major controlling east-west shear zones that have been reactivated in different senses throughout geological history is the result of careful examination of the data. The dominance of such systems is not obvious on simple fault maps. Their role in the regional plate tectonics fits the model of escape tectonics of the North Sea-Baltic plate. The distinction of different styles of Late Carboniferous normal fault systems results in a better understanding of the different tectonic phases during the period from Westphalian D to Autunian.

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.
