Abstract
A quantitative and qualitative distribution of the foraminiferal and ostracods obtained from a 80 cm length core implanted in Gargour coastal fringe (Southeastern of Tunisia), shows various species. The benthic foraminifera, are composed of two assemblages, (1) Coastal marine assemblage comprising Elphidium crispum, Elphidium advenum, Quinqueloculina bicostata, Quinqueloculina seminula, Adolisina sp., Sorites orbiculus, Peneroplis perstus. (2) Brackish estuarine influences assemblage containing Ammoniana tepida, Ammonia parkinsoniana and Trochamina inflata. The ostracods show three associations, (1) Marine assemblage containing Aurila woodwardii, Semicytherura striata and Loxoconcha rhomboidea. (2) Lagoonal assemblage made up of Leptocythere fabaeformis and Xestoleberis aurantia. (3) Estuarine influences brackish assemblage comprising Cyprideis torosa, Loxoconcha elliptica and Loxoconcha turbida. Three major zones (I, II, and III) were identified based on dominance of ostracods and benthic foraminifera assemblages, coupled with sedimentary facies.
