Rheology and Deformation of the Lithosphere at Continental Margins is a collection of well-written and interesting papers that provide a good overview of the current cutting edge in seismically oriented deformation studies. The book is, unfortunately, somewhat misnamed. It really should be titled something akin to A review of seismogenic behavior in different plate tectonic settings (and some partially molten mantle deformation experiments). Perhaps it sounds less impressive, but that is really what you get in this bookc a series of excellent review papers, most of which focus on our current understanding of seismogenic behavior. The book had its genesis at a short course and workshop in 2000 held in Snowbird, Utah, associated with the MARGINS initiative. For this volume, there are three papers on divergent settings (Buck, Axen, Davis and Kuznir), three on convergent settings (Jackson, Hyndman, Willet and Pope), and two on transcurrent settings (Chester et al., Scholz and Hanks). In addition, there is an excellent overview on the seismogenic zone by L. Ruff (which should be read first and probably should have been placed there). All of these articles, with the exception of Willet and Pope, are primarily interested in seismogenic deformation. The above fit neatly into a volume that is focused on information gathered from seismic data. The papers that do not fit neatly into the above scheme are the last two papers in the volume, written by experimentalists working on partially molten behavior of mantle rocksc Xu et al. and Evans et al. Both papers are very good reviews of the subject and hopefully will not be overlooked because they are different from the dominant theme of the book.
