| Abstract |
The magnetic anomaly pattern over the Red Sea can be modeled as a continuous system of sea-floor spreading from the early Miocene to the present by using a time-varying process filter. Application of a time-varying process filter appears to be a powerful tool in analyzing magnetic anomalies over passive continental margins. The flow parameter is estimated to be 2.7 km (1.7 mi) and the intrusion parameter to be 7.5 km (4.7 mi) at early rifting. These values suggest that a side distribution of axial dikes or horizontal strain is the dominant factor in forming the magnetic anomaly pattern. Reduction in the width of the intrusion parameter and the effusion rate as rifting proceeded resulted in focusing of the strain, thinning of l ayer 2, and formation of the Red Sea deeps. |
