ORIGIN OF THE LOUISVILLE RIDGE AND ITS RELATIONSHIP TO THE ELTANIN FRACTURE-ZONE SYSTEM

Abstract:

We have combined shipboard and Seasat altimeter derived data in an integrated geological and geophysical study of the Louisville Ridge; a 3500-km-long seamount chain extending from the Tonga trench to the Eltanin Fracture Zone.
