The authors’ works concern the sediments of the upper part of Tortonian
within the basin of El Ma Labiad located at the southern part of Tebessa city,
belonging to the eastern saharian Atlas mountains chain on the Algero-
Tunisian borders.
The se
dimentological analysis, carried out on 120 samples, has confirmed a
downlap development structures towards the West of the basin. These analyses
have also proved the presence of a detrital continental sedimentation of four
environments characterized by the river, delta, lake and marsh materials.
The petrographic and morphological analysis reveal a clastic sediments
essentially quartz-bearing interbedded by some argillaceous intercalations, and
a far-off water transport of an origin probably saharian.
