  abstract = {{A} detailed stratigraphic analysis was carried out on {V}alanginian deposits of six {M}oroccan sections of the {E}ssaouira-{A}gadir {B}asin ({EAB}, {S}outh {T}ethyan margin) in order to characterize the {W}eissert {E}vent and propose correlations with the {N}orth {T}ethyan margin (southeeast {F}rance {B}asin). {T}he studied successions consist of alternating marlstone and limestone beds with sandy intercalations, and are well exposed and relatively rich in ammonites. {A}mmonite biostratigraphy and sequence stratigraphy were established for all successions, whereas calcareous nannofossil and carbon stable isotope analyses were performed for two and five sections, respectively. {F}or each succession, an accurate ammonite zonal scheme allows to recognize the standard zonation established for the {M}editerranean {P}rovince. {A} calcareous nannofossil zonation is provided for {Z}alidou and {A}{\¨ie}t {H}amouch, considered as reference sections. {T}he detailed biozonations allowed to ascribe an accurate age for most of the sedimentary discontinuities and depositional sequences identified in the {EAB}. {E}astewest and northesouth transects are established for the {V}alanginian depositional system. {D}espite some stratigraphic gaps, the {V}alanginian carbon isotope excursion ({CIE}) was recognized in most of the studied sections. {T}he {M}oroccan successions are correlated with those of reference sections of southeeast {F}rance i.e., the {V}ocontian {B}asin ({V}ergol-{L}a {C}harce) and {P}rovence {P}latform ({C}arajuan), using bio-sequence-chemo-stratigraphy. {T}hese inter-basin correlations allowed to evidence major 'mid-{V}alanginian' and upper {V}alanginian eustatic regressions; the possible role of tectonics and glacio-eustacy is also discussed.},
