Ifounassene section (Unit 3), Morocco (Miocene of Morocco)

Also known as Ifounassene section (lower), Morocco

Where: Morocco (35.3° N, 3.0° W: paleocoordinates 35.2° N, 3.2° W)

• coordinate stated in text

• local area-level geographic resolution

When: Messinian (7.2 - 5.3 Ma)

• Data a composite of sampled horizons with lower unit of sequence. No formal lithostratigraphic names used in text. Dated tuffs within unit yielded an ages of 6.29 +/- 0.02 Ma.

• group of beds-level stratigraphic resolution

Environment/lithology: diatomaceous marl and limestone

• "The Melilla-Nador basin is one of the post nappe basins of the Rif region created during sun-Tortonian extensional period. Late Tortonian and Messinian deposits are widely transgressive over the tectonized bvasiment and lower part of the Messinian deposits is characterized by southward prograding shallow water bioclastic then reefal complexes, changing to open marine marls and diatomites
• Described in text as "thin laminated diatomiytic marls with fish remains, with carbonate bioclastic limestones". Unit 3 in text is a "a prograding Porites reef complex, including Halimeda-rich slope deposits which extend far basinward".

Size class: macrofossils
