The Algerian sedimentary phosphorites of marine origin are located mainly in the Tébessa
region, which is part of the Eastern Saharan Atlas. These phosphorites are hosted by
Paleocene-Eocene series and crop out in two main sedimentary areas: the northern sites
(Djebel El Kouif, Djebel Dyr and Djebel Tazbant) and the southern sites, which include the
Djebel Onk commercial world-class ore deposits that are represented in this study by the Kef
Essenoun sector. This study reports a detailed investigation of these phosphorites at a …
