Abstract: In the light of current ideas on the western Mediterranean back arc-thrust system,the Mlocene sedimentation in the Ragglo di Calabrla area was studied.With a local provenance,the Miocene sedimentation started with local deposition of coarse-grained subaerial sediments in the form of alluvial fans.These rapidly evolved to a fan-delta-turbidite facies association.The synsedimentary structures locally affected the sedimentation.The Miocene sedimentation was terminated at about Messinian time due to the regional tectonic.
