A Seismic Facies Analysis to Determine the Relative Age and History of the Al Idrissi Mud Volcano from Offshore Larache Located in the NW Moroccan Atlantic Margin

Formed on top of the Gulf Cadiz, Al Idrissi mud volcano is shallowest and largest in El Arraiche field northwestern Moroccan margin. The development morphology volcanoes from group have been studied at a large scale. However, time interval related to their formation period still needs be better understood. In this regard, we interpreted analyzed seismic facies 2D reflection data GEOMARGEN-1 campaign, which took place 2011. aim was identify sequences draw system determine Idriss volcano. And as result, made both buried superficial bicone identified along with Upper Tortonian Messinian-Upper Pliocene facies. As initial extrusive edifice, formed Late-Messinian Early-Pliocene period. bicone, final included Late Pliocene. case, timing between equivalent Upper-Pliocene Therefore, latter corresponds
