Objectives
2 Validate the timing of ophiolite generation using radiometric dating of volcanic and plutonic rocks and apply igneous geochemistry to check correlations. 3 Apply palaeomagnetic techniques to determine the latitude(s) at which these rocks formed. It might also be possible to use to the horizontal components of magnetization (declination) recorded by each of the suites to enhance the tectonic modelling. 4 Use the data from objectives 1-3 to model the Neotethys' development over the interval spanning the Late Jurassic to earliest Eocene. We might also be able determine the plate configuration at the time of subduction initiation, and thus contribute to the broader debate associated with subduction initiation in intra-oceanic settings.
