Figure 5-9 



Magnetic anomaly chart of the Gorda Rise area. Positive 

 anomalies are shown in black; negative anomalies are shown 

 in white. The northeast-southwest trending Gorda Rise is 

 obvious as is the northwest-southeast trend of the Blanco 

 Fracture Zone near the northern limit of the chart. Compare 

 the inferred "propagator wake" (indicated by dashed lines) 

 to the theoretical model of a propagating rift illustrated 

 in Figure 5-8.
