Type: article
Abstract: Niger imports a huge quantity of bentonite, which it uses in mining and oil exploration, but also in village hydraulics. The objective of thisstudy is the search for a bentonite-type clay deposit on the Nigerian territory. The clay fraction of a material collected on a clay depositof the Paleocene Garadaoua Formation in the Ullemmeden basin (central Niger) was the subject of a series of analyzes: DRX; ICP-AES;ICP-MS; ATD-ATG; IR; Adsorption/desorption of N2 at 77 K; cation exchange capacity, granulometry. DRX results corroborated bythose of IR and ATD-ATG indicate that the clay minerals constituting the collected material are: montmorillonite, kaolinite and illite, witha strong predominance of montmorillonite. The mineralogical and chemical composition, the specific surface and the cation exchangecapacity obtained indicate that the analyzed material is similar to that of Maghnia bentonite in Algeria.
