	The Algero-Tunisian confines (Tebessa region) belong to the southern Tethyan domain and the Monts Mellegue. This region is partly composed of Cenomano-Turonian carbonate outcrops; therefore, the investigated sections\&nbsp;highlight the black shale levels reported over a short period, around the Cenomanian-Turonian boundary. The lithostratigraphic study designated a depositional environment that emphasized a relatively deep, calm, and often confined ocean environment significantly shallower on the northern part of the study area. The facies lithology and distribution leads\&nbsp; to underline the pelagic influences during the upper Cretaceous and neritic throughout\&nbsp;the lower Cretaceous period. The\&nbsp;maximum thickness of the Cenomano-Turonian (1000\&nbsp;m) was recorded\&nbsp;in the southern zones and the\&nbsp;minimum (100\&nbsp;m) occurred\&nbsp; further north. This palaeogeographic organization persists\&nbsp;laterally in Tunisia as\&nbsp;the extension of the Constantine mole. The geochemical analyses reveal\&nbsp;that the maturity of the Cenomanian source rock is variable. Nevertheless,\&nbsp;the Turonian source rock \&nbsp;seems to be\&nbsp;at the beginning of the oil phase.
