1995 · GE-314 — Berlin Heidelberg: Springer-Verlag 1995. Comprehensive text presents the combination of the most recent oceanographic data with ophiolites representing fossil ocean crust obducted onto the continents by tectonic processes. The existing oceans are geologically relatively young. They formed when a large supercontinent Pangaea broke apart some 150 Ma ago. The mid-oceanic ridges are narrow belts of submarine mountains marking the boundaries between plates which are moving apart with new oceanic crust being created at the same time. Under the continents oceanic crust is subducted. The ocean bottom is an ideal location to study recent geodynamic processes on Earth. Topics covered include plate kinematics; hotspots and mantle plumes; submarine topology and exploration; ophiolites; mantle metallurgy; ridge dynamics; oceanic rocks; mantle diapirism and segmentation; expansion of rifts; etc. 200 pgs.
