The Oman-UAE ophiolite is often viewed as the classic example of oceanic crust formed at a fast-spreading mid-ocean ridge, directly comparable to modern spreading centres such as the East Pacific Rise. However, recent work by the supervisors of this project has demonstrated the pervasiveness of subduction-related geochemical signatures: the early part of the ophiolite sequence is shown to have formed at a spreading axis above a newly-forming subduction zone (MacLeod et al. 2013), then intruded by a (slightly) later, voluminous, subduction-related magmatic sequence that forms up to 50% of the crust in the northern part of the ophiolite (Goodenough et al. 2010).
The student will have the opportunity to work in a superb natural laboratory with a fully exposed, easily accessed field area where structural and igneous relationships can be examined in 3D, and to gain training in many aspects of both structural and igneous geology. He/she will learn to use a variety of analytical techniques in the labs at Cardiff and BGS. He/she will also have access to training courses within both the BGS portfolio and GW4 DTP partnership, and will be part of strong cross-institute research groups in Cardiff focusing both on the development of oceanic crust and on subduction zone processes.
