Volcanic and tectonic control on slow spreading ridge geometry using key sections of the mid-Atlantic ridge

Objective



This project will examine the configuration of the worlds longest secti of slow spreading boundary, the Mid-Atlantic Ridge, to determine the structural and magmatic inputs which control the spatial and temporal evolution of the ridge. In detail, a number of first order ridge segments will be studied by interpretating bathymetric and imagery data held at IOSDL to assess influence of hot-spot activity and/or spreading rate and direction changes.
Three contrasting areas have been selected:
?magmatic, influenced by Azores and Iceland hot spots
?'normal', as the segment south of Atlantis Fracture Zone,
?tectonic, influenced by the large equatorial fracture zones. The principal objectives are:
1) To detennine the statistics of 2nd order segmentation
2)To assess the spatial and temporal ridge variation
3) To compare the tectonic and volcanic ridge characteristics
4) To develop a model to explain the geological controls on slow spreading ridge geometry.
