This book forms the second of a two part volume containing a compilation of 35 classic papers on extensional tectonics, with particular emphasis on petroleum-related features. Each part comprises a set of scientifically significant papers from the last 20 years taken from the Journal of the Geological Society and various Special Publications of the Geological Society. The present volume focuses on faulting and fault-related processes under the headings: Geometry and Spatial Attributes of Normal Faults; Active Normal Faulting and Seismicity; Analogue Modelling; and Intra-Reservoir Faulting and Fluid Flow. The book begins with a new scientific and historical review of the subject and the context of the papers contained therein.
