Evolution of the Pyrenees during the Variscan and Alpine Cycles 1 presents the evolution of geological knowledge of the Pyrenees as a result of major scientific research programs in the early 21st century. This book, dedicated to the Variscan cycle and Cretaceous rifting, traces the evolution of the Pyrenean domain between 340 Ma and 90 Ma. It begins with an analysis of the state of knowledge of the Pyrenean basement, whose structure is inherited from the Variscan evolution of this domain. It then traces the kinematic evolution of the western Mediterranean domain since the Paleozoic. Finally,…mehr
Evolution of the Pyrenees during the Variscan and Alpine Cycles 1 presents the evolution of geological knowledge of the Pyrenees as a result of major scientific research programs in the early 21st century. This book, dedicated to the Variscan cycle and Cretaceous rifting, traces the evolution of the Pyrenean domain between 340 Ma and 90 Ma. It begins with an analysis of the state of knowledge of the Pyrenean basement, whose structure is inherited from the Variscan evolution of this domain. It then traces the kinematic evolution of the western Mediterranean domain since the Paleozoic. Finally, it discusses the evolution of our knowledge of Cretaceous rifting and the sedimentary and metasomatic processes associated with the individualization of the Iberian-Eurasian plate boundary.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
Nicolas Saspiturry is a teacher-researcher specializing in the tectonic-sedimentary and thermal evolution of sedimentary basins. He has devoted much of his work to the Pyrenees. Jessica Uzel has a doctorate in geology and a degree in life, earth and universe sciences. She specializes in the post-compressive evolution of the Pyrenean domain. Alexandre Ortiz has a doctorate in geology. He specializes in the syn- to post-compressive evolution of the North Pyrenean foreland basin.
