Transform tectonics of the West African Margin explored


  • ODP Leg 159 Scientific Party


The first detailed record of the sedimentary and structural evolution of a transform passive margin was recently obtained during ODP Leg 159 on the west African margin. Four sites (sites 959–962) were drilled into continental crust along the prominent marginal ridge that defines the continental margin. The record documents the deformational regime that existed during the early active transform phase and the response of the margin to later thermal rejuvenation.
