Abstract
The palynological content of South-East Constantinois Cretaceous sedim ents, belonging to Gafsa, Zebbag and Aleg Formations, and collected in the Manndra 1 and Oued Melah 1 bore-holes, is investigated. Two serie s of intervals, one based on dinoflagellate cysts, the other on spores and pollen, are defined for each well. The vertical distribution of s ome species, precisely known in other areas, allows us to give an age to most intervals, and consequently to each formation: Barremian?-Albi an p. p. for the Gafsa Formation, Albian p. p.-Cenomanian for the Zebb ag Formation, Turonian-Santonian or Campanian for the Aleg Formation. These results are compared to foraminifera data.
