INTERNAL STRUCTURE OF FAST-SPREAD OCEANIC CRUST
Bathymetric map of the fast-spreading East Pacific Rise, spreading segments, transforms, overlapping spreading centers, and abyssal hills.
Generalized columnar section of the upper oceanic crust.
Examples of major rock units exposed in tectonic windows in fast-spread crust.
Summary of the geology of the upper oceanic crust based on investigations of tectonic windows and deep crustal drilling.
Schematic diagram summarizing inferred spreading processes at fast-spreading mid-ocean ridges. Subsidence and tilting of lavas and sheeted dikes requires dramatic mass redistribution in the underlying axial magma chamber (AMC) and low velocity zone (LVZ).
Summary of spreading processes at fast-spreading mid-ocean ridges based on available geological and geophysical information.
