| The stratigraphy and structure of the old, starved passive margin of the Mazagan Plateau and the adjacent Escarpment which extends from 1,000-3,000 m water depth was studied during the cofinanced French-German CYAMAZ deep diving campaign which obtained 130 in-situ samples, supplemented by direct sea floor observations during 18 dive traverses. The facies evolution of the Mazagan carbonate platform between kimmeridgian and Valanginian times was mainly influenced by blockfaulting and sea-level fluctuations. Regressive periods occurred during Kimmeridgia/Tithonian and Late Berriasian times, and are separated by a late Tithonian/early Berriasian transgression. The drowning of the main carbonate platform and the Early Cretaceous to Paleogene history of the... |

| The micropaleontological content (calpionellids, foraminifera, algae) of the samples collected during the CYAMAZ campaign (1982) from the Jurassic platform of the Mazagan Plateau allows their attribution to upper Malm (but the lowermost Neocomian cannot be excluded completely). These samples are compared with the DSDP Leg 79 ones and those coming from numerous onshore outcrop sections. That comparison shows that CYAMAZ samples are very similar (if not identical) to those of the top of the Jurassic platform in site 545 and in Western High Atlas sections. |
