Provenance and sedimentary processes on Pleistocene storm deposits in Harhoura (Northern Coastal Atlantic, Morocco): New constraints from a source to sink perspective

The present work studies the Harhoura coastal deposits located immediately southwest of Rabat, Morocco. The base of this sequence has been previously dated by 14C as 9900 ± 150 BP. These deposits exhibit a thick record potentially related to the footprint of a high-energy storm. They are primarily characterized by coarse-grained dark shelly/gravelly units bearing highly fragmented shells inherited from shallow water platform. A high amount of organic matter was also observed.
