Rifted Ocean-Continent Boundaries covers a wide range of topics, from quantitative modelling to current knowledge of the structure and evolution of specific margins around the world. Special emphasis is placed on the structure and evolution of various Atlantic margins.
After an introduction to volcanic margin concepts, the first articles report the results of numerical models of the mechanics of rift propagation, melt generation and sources of extensional stresses that may cause break-up. One part of the book is dedicated to current knowledge of the structure and evolution of various Atlantic margins. After a brief incursion into the Mediterranean, succeeding articles report on the transform and active margins of the Ivory Coast-Ghana transform margin and the Sea of Japan.
