Abstract: This study focuses on the reconstruction of the depositional environment of the Paleocene limestones of the Iullemmeden sedimentary basin in the Malbaza region. The methodology used is based on a petrographic and palaeoenvironmental study. The Palaeocene limestones of the Iullemmeden basin are zoogenic and show rapid facies variations. The petrographic description reveals three levels: slightly clayey chalky limestones, massive limestones and nodular limestones. The study reveals that the limestones at Malbaza have mudstone and wackstone textures. The depositional environment is a shallow, less agitated platform.
