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,...

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...

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 hyper-extended Eastern Sardinian margin is due to the eastward migration of the Appennine-Calabria subduction zone, creating the Neogene back-arc Tyrrhenian Basin. This area was affected by strong erosion during the Messinian Salinity Crisis (MSC, 5.97 - 5.33 Ma) on the continental shelf and slope leading to a major discontinuity, known as...

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...
