ResumoThe Tamga mountain range system is characterized by Holocene diatom-rich deposits, located along the nvers Oued El Abid and Tidjikja, dated between 9 630 14C B P and 7 550 I4C BP. The diatom studies provide the reconstruction of the palaeoenvironments of the wadi flood plain, composed of small lakes separated by narrow still water reaches. The results evidence a humid phase at 9 000/8 000 14C B P , followed by drier conditions after 8 000 I4C BP.
