Deep Drilling Project in the Forearc of the Hellenic Subduction Zone

Europe, Mediterranean Sea, Greece, Crete, Hellenic Forearc

new workshop-proposal: ICDP-1998/06
for the funding-period starting 1998-01-15
by Dimitrios Papanikolaou
Abstract
This pre-proposal serves the preparation of a joint Ocean and Continental Scientific Drilling Program that comprises several drillholes into the Hellenic forearc, on Crete and offshore to the south and southwest. The Eastern Mediterranean Hellenic forearc is a well constrained example of a retreating subduction zone. In the late Tertiary a microcontinent collided with the subduction zone, sedimentary cover rocks were scraped off and high-pressure and low temperature metamorphic suites were exhumed rapidly. The present position of the remaining continental mass is uncertain but existing models suggest thinning through radial and tangential extension leading to extremely thinned microcontinental crust below the present forearc system. Anyhow, the mechanics, the coupling between plates as well as the present crustal structure and the geodynamic evolution remain as fundamental problems. These questions are tackled by the research program. A workshop is planned for October 1998 to evvaluate the potential correlated onshore/offshore drilling prohgram within the scope of a future Earth Drilling Program (EDP). Presently the PIs of this proposal request for $ 30 000 for the preparation and conduction of the planned workshop.
