After summing up the notes of earlier authors (, 1970, 1972), we propose herein a new holostratigraphic definition for this unit, i.e., a definition based on our faciological, lithostratigraphical, sequential, and paleontological analyses.Typiquement sud-tthysiennes, elles facilitent les corrlations holostratigraphiques haute rsolution avec la rgion du Golfe persique, sur le ct oriental de la Plaque arabique.L'intervalle Jezzinien correspond ainsi la partie suprieure de l'Étage Rgional Kharaibien (aussi connu comme unit rservoir "Thamama II" dans l'industrie ptrolire).
