| Popis: |
The PLURIEL cruise (Marion Dufresne II, 19 September 31 October 2006) had as main objective the study of the temporal evolution of the interaction between the St Paul-Amsterdam hotspot (SPA) and the Southeast Indian Ridge (SEIR) over the last 15 m.y.. The SPA-SEIR system is an ideal target to study the transition of hotspot activity from an intraplate to an axial context. North-east of the SPA plateau, which corresponds to the axial activity of the hotspot, a chain of volcanoes possibly marks its intraplate activity. The most recent volcanic activity is located east of the Amsterdam island, very close to the ridge axis. The first results of the cruise show that the time evolution of this ridge-hotspot interaction is very complex. |
