Roller-bearing tectonic evolution of the Juan Fernandez microplate

A combined GLORIA sidescan and Hydrosweep multi-narrow-beam sonar survey shows striking evidence for fan-shaped spreading systems, bounding pseudofaults and compression ridges associated with 90° of clockwise ...

Comprehensive sonar imaging of the Easter microplate

Recent GLORIA and SeaMARC II sidescan sonar surveys have imaged virtually the whole of the Easter microplate, and revealed unprecedented detail and complexity in its tectonic fabric and history. There is clear...

Fanning of fracture zones and a three-dimensional model of the Mid-Atlantic Ridge

Present-day spreading directions as represented by the active (transform fault) sections of fracture zones in the central North Atlantic do not fit a small circle pattern about a unique pole^1–5, as recently confi...

Lateral Extension in the East African Rift Valleys

MCKENZIE et al.¹ have proposed a pole position and rotation angle to describe the opening of the East African Rift Valleys. On the basis of this rotation, they expect extensions of about 30 km in Kenya and 65 km ...

Evolution of Rifting in Africa

Studies of seismicity, age of faulting, age of volcanoes and short and long wavelength gravity anomalies all indicate that the evolution of the East African rift system is related to attenuation and early stag...
