  abstract = {{A} geological study carried out in the {B}omkoul area ({D}ouala sub-basin, {C}ameroon) has revealed the presence of heterogeneous clayey materials on hills (80-120 m altitude). {T}he clay deposits are thick at the upper slope where sandstones and sandy-clay overlying clay layers, and thin at the middle and lower slopes where weathered clays overlying clay layers. {C}layey materials identified are grey, dark-grey and mottled in color, with sandy-clay, clayey-silt, silty-clay and clay textures. {R}aw materials are mostly made up of fine particles ranging from 52 to 82% clay and silt in the mottled clayey material, 50 to 82% clay and silt in the dark-grey clayey material and 70 to 85% in the grey clayey material. {T}heir chemical composition is characterized by silica (<70% {S}i{O}2), alumina (<32% {A}l2{O}3) and iron (1 to 16% {F}e2{O}3). {T}he main clay minerals are disorganized and poorly crystallized kaolinite and few smectite. {T}he physical, mineralogical and geochemical properties of these materials presented and discussed in this work show that the clayey raw materials of the {B}omkoul area have a good potential for pottery as well as brick, tile and soil sandstone manufacture.},
