Le projet METYSS (Messinian Event in the Tyrrhenian from Seismic Study) concerne le bassin tyrrhénien occidental le long de la côte est-sarde et s'intègre dans le cadre d'une étude comparative des marqueurs sismiques de la Crise de Salinité Messinienne (CSM) à l'échelle du bassin méditerranéen. La mer tyrrhénienne est un bassin arrière-arc...

In the last fifty years, the Messinian Salinity Crisis (MSC) has been widely investigated in the Mediterranean Sea, but a major basin remains fewly explored in terms of MSC thematic: the Western Tyrrhenian Basin. The rifting of this back-arc basin is considered to occur between the Middle-Miocene and the Early-Pliocene, thus including the MSC,...

The Tyrrhenian Sea is usually interpreted to be a Neogene back-arc basin that opened by continental rifting and oceanic spreading caused by the eastward migration of the Apennine subduction system from Tortonian to Pliocene times. Rifting of the Tyrrhenian Sea started first along the Eastern Sardinian margin during the Tortonian-Messinian...

The Tyrrhenian Sea is usually interpreted to be a Neogene back-arc basin that opened by continental rifting and oceanic spreading caused by the eastward migration of the Apennine subduction system during Miocene and Pliocene times. Rifting of the southern Tyrrhenian Sea started first along the Eastern Sardinian margin during the middle to late...

The Messinian salinity crisis (MSC) is characterized by gigantic erosion that remodels the margins while a thick, essentially evaporitic and detrital, sedimentary sequence forms in the deep basins. Based on recent (MAURESC, 2003) and earlier (MESEA 1, 1990; MAGIRAA, 1996; GEOBREST, 2002) seismic reflection data, this work brings to light the...

The current interpretation of the Messinian Salinity Crisis (MSC) involves the deposition of peripheral or marginal evaporites in onshore basins as well as the erosion of the margin and the deposition of thick evaporites in deep basins. The so-called intermediate basins are formed in domains between the onland outcrops and the deep basins. The...

The Eastern Sardinian margin consists in a hyper-extended rifted margin, located in the western Tyrrhenian Sea, a recent back-arc basin (late Neogene). This area was affected by strong aerial erosion during the Messinian Salinity Crisis (MSC, 5.96 - 5.33 My) associated with the drop of sea level (> 1500 m) which occurred throughout the whole...

La marge orientale de la Sardaigne est une marge continentale passive hyper-étirée, située en Mer Tyrrhénienne occidentale, en contexte d'arrière arc récent (fin Néogène - Quaternaire). Cette région a été affectée par une forte érosion aérienne pendant la Crise de Salinité Messinienne (CSM ; 5,96 - 5,33 Ma) associée à une baisse importante du...
