[ED: Taschenbuch / Paperback], [PU: Springer, Berlin], KURZE BESCHREIBUNG/ANMERKUNGEN: Prepared under the aegis of the I.G.C.P. 227 AUSFÜHRLICHERE BESCHREIBUNG: The African continent is unique in that it has escaped widespread orogenic activity after the Pan African orogenic event. Therefore, the African Plate provides the world's best example of the relationship between extensional magmatism and structural setting. This first complete and up-to-date review, written by leading scientists, discusses the evolutionary model and offers a new and reliable basis for scientists working on plate tectonics and extensional areas in other continents.
