CHAPTER 4

Mid ocean ridges (MOR)
structure of normal oceanic crust
ophiolites

we have discussed submarine ridge
topography on various length scales….

slow

Topography of slowly spreading MOR
Example: Sounth-Indian Ridge
View towards the W at 116°E, ca. 80 km
from B. Haxby (1998) Geoph. Monogr. 106

Topography of fast spreading MOR
Example: East-Pacific rise (EPR) at 7°S
View towards South over ca. 160 km
from B. Haxby (1998) Geoph. Monogr. 106

Dredging
Diving
Drilling
All other information comes from geophysics
(topography, seismology, magnetics …..)
