Meeting of the present members of the Steering Committee in order to discuss impending strategic
issues

SUMMARY:

After all participants had presented their plans, the links between the projects and the potential gaps have been discussed. The links were rather clear. The planned geophysical experiments will help to revise the conceptual models of breakup used in structural geology and basin analysis. Geological work is including both onshore and offshore areas on both conjugate margins and denudation studies complement subsidence analyses offshore. Regional focus is partly dependent on data availability and partly on existing results from specific areas for which no new work is required.

The missing field of geomorphology can easily be compensated via external collaboration with TOPOAFRICA and with South African and South American partners, which however needs detailed reference in the proposals. The ultimate aim is to link the magmatism as signal of mantle activity with onshore denudation, offshore subsidence, sedimentation pattern evolution, gas emission, atmospheric and oceanic circulation as well as global plate movements and related far field effects.
Key aspects for phase II and III are:

• How does continental breakup work and which is its magmatic signal?
• Why is the post-breakup evolution on both sides of the South Atlantic so different?
• What are the far-field effects (plate tectonics, mantle convection, ocean circulation) on the system?
  

We aim to establish consistency checks between different viewpoints related to different disciplines and find answers for complementary fields. Examples are: which circulation/depositional/structural pattern would result from which plate-tectonic/mantle convection setting?

Also the question if a protected but shared data management is desirable has been raised and which form would be most efficient. The consensus reached was that it is considered as very important and helpful and should be submitted as a separate proposal with a coordinative aspect.

A formal issue concerned the proposal submission procedure. After discussion the following proposal was put forward:

• to submit directly to DFG according to the rules of proposal submission
• to send a copy of each proposal to the main coordinator (H-P. Bunge)
• to circulate the summaries of the proposals within the community at least two weeks before submission deadline to facilitate clarification of links between the proposals
• the coordinators will compile a white paper summarizing the main goals of phase II one month before submission deadline.
  

Another formal issue concerned the strategy of submitting two (18 +18 months) proposals or one 3-year proposal and the conclusion was that this depends on the progress in the individual projects.

Begin at 13:00, end at 17:00
The first half was reserved for short project reports and discussions.
The second half was for general discussion about links and cooperations within the petrology projects and with geophysics and modelling groups, and strategies for the next phase.

Important points identified include:
a) Unifying theme for petrology projects: “Mantle-derived magmas and their interaction with crust” with a common goal to trace the magmatic record from pre-breakup (Etendeka) to post-breakup (evolution of the Walvis Ridge)
b) 3 priority topics where all projects can contribute samples, analytical experience and equipment: Geochronology (Kiel), Melt inclusions (Potsdam), Magmatic volatiles (Tübingen)
c) there is an urgent need for information from SPP coordinators about the next phase of proposals. What is the duration of the next phase, and must it be the same for all projects? If the next phase is 3 years for all, is there a recommendation for ongoing projects - 18 months to finish the current phD, and the remaining 18? A limited set of options will help proponents and reviewers.
