Structures of Ophiolites and Dynamics of Oceanic Lithosphere

About this book

Ophiolite are section of the Earth's oceanic crust and the underlying upper mantle that have been uplifted and exposed above sea level and often emplaced onto continental crustal rocks. This book describes typical formations, how these geological structures are formed, and how geophysical processes around oceanic ridges contribute to their formation.
