Typologie, architecture et origine des structures d'émission de fluides et leurs interactions avec les processus sédimentaires et tectoniques. Exemple de la Méditerranée Orientale

Abstract : Since the early 80s, technological advances of seabed imagery and exploration of continental margins allowed to discover and study numerous seabed features recording fluid circulation within the sediment column.In this study of mud volcanoes, we propose an innovative method of analysis combining an automated statistical approach including detection and analysis of morphometric parameters together with a classical geological study. We used broad homogenous academic and industrial marine geophysical and geological dataset, at the scale of Eastern Mediterranean sea.The analysis of these parameters shows that the mechanism of formation of the mud volcanoes is directly related to a local or regional constrain that may have a tectonic or gravitational origin.Various geological parameters conditioning the size and shape of mud volcanoes have been studied and lead to propose an original model for the formation of mud volcanoes. The design of this model, which is intended to be generic, makes it possible to group the constituent parameters of a mud volcano system in three spatial stages, from the source layer to the superficial expression.
